One of the biggest scandals in Hollywood history was when actress Kristen Stewart cheated on her boyfriend, Hollywood superstar Robert Pattinson. The couple dated for three years before they got married in 2014. But their relationship was always shrouded in controversy, and even after they got married, the stories kept on coming thick and fast.

Most recently, Kristen admitted that she had cheated on Rob with her Twilight co-star, Taylor Lautner. The pair reportedly had an affair while filming the last two films in the vampire saga. But how did Rob find out?

Here’s a detailed timeline of what happened.

A Brief Romance

It all began in 2013 when Rob and Kristen began dating. The couple went on several romantic dates but never made it to the altar due to Rob’s busy schedule. The actor reportedly told Us Weekly in May 2015 that he and Kristen had been dating for “about a year” at the time. They kept their relationship a secret from the public and were rarely photographed together.

Their first official public appearance as a couple was at the American Film Institute (AFI) Fest in late September 2013. The following month they were photographed attending the 2013 Vanity Fair Oscar Party together. Another AFI Fest event, this time in October, saw the couple share an onstage kiss.

But it was during the final season of Rob’s stint on The Twilight Saga: Breaking Dawn – Part 2 that his relationship with Stewart took a serious turn for the better. While filming the second part of Breaking Dawn in early 2014, Rob reportedly decided to leave the series on a high note and propose to Stewart. The couple had been keeping their romance a secret throughout the entire shoot, but decided to make it public in a big way when filming wrapped.

As previously reported by USA Today, Rob proposed to Kristen at the SAG Awards in January 2014. The following month, Rob and Stewart made their official red carpet debut at the 2014 Golden Globes. Though the star had a band around his neck, the proposal took place right in the middle of the ceremony. The audience was treated to an emotional moment as Robert asked the question, “Will you marry me?”

The couple continued to keep their relationship a secret for the rest of the year, making only occasional public appearances together. But in September 2014, they attended New York City’s annual Comic-Con event, where they were photographed holding hands while sitting on a couch together. It was during this appearance that fans first learned of the romance. But the couple still refused to confirm their relationship until November 2014, when they attended the Hollywood Film Awards, where they were seen holding hands and enjoying a romantic date night out. Finally, in December 2014, the couple made their relationship official when they were photographed leaving Stewart’s home in a wedding dress.

The year 2014 was a big one for Rob and Kristen, as it was their year of becoming engaged and eventually getting married. They spent most of the year planning their fairytale wedding. In April 2015, they held a wedding ceremony in an intimate garden setting at the Chateau Marmont in Los Angeles. The couple’s good friend and Twilight co-star, Taylor Lautner, who is also Taylor Swift’s brother, officiated the ceremony. The happy couple subsequently released a joint statement confirming their commitment to each other.

Their fairytale romance was finally made public in May 2015 when Rob and Kristen began appearing together as a couple on the big screen. The following month, Rob’s publicist, Natalie Pyle, announced the couple were engaged. But while on the set of the movie The Nice Princess – about a young woman who assumes the role of a princess to fulfill her dreams – Rob’s rep confirmed the engagement was purely “PR.”

The Scandal Continues

Despite their whirlwind romance and ensuing engagement, things weren’t perfect between Robert and Stewart. The couple’s relationship was always going to be dogged by scandal, and it continued into their marriage. In September 2015, Rob’s rep revealed the couple were having marital problems and that they were spending more time apart than together. Though they were committed to each other, their time together was “bumpy,” according to the representative.

Shortly after this, it was reported that Rob had filed for an annulment. While a rep for Rob denied the request, it wasn’t long before the media were reporting that he and Kristen had indeed gone through with the divorce. Finally, in April 2016, three months after their split, the duo issued a joint statement confirming they were still together and had simply “decided to go our separate ways.”

But they were never truly separated, and it was clear that their relationship was still incredibly important to both parties. In June 2016, the couple were seen attending the Cannes Film Festival together. And in September 2016, they were photographed attending the MoMA (Museum of Modern Art) Film Week in New York City. The following month, Rob’s rep released a lengthy statement confirming their relationship was “on the mend.”

Just last week, Rob and Kristen were spotted out together in London. The couple have been relatively quiet since the split, but it wouldn’t be the first time they were spotted on the red carpet, showing they had not ruled out a reconciliation. In any case, for now, it looks like their romance is over but they remain committed to each other. And for that we can all be (relatively) happy. That is, as long as they don’t mess up our fandom by getting back together again (which, let’s face it, they probably won’t).

So, what happened? Well, let’s take a look back at the timeline. As you may have guessed, a lot of scandalous events transpired in the years preceding this story.

Robert Pattinson Dates Kristen Stewart

It all began back in 2011 when Twilight star Kristen Stewart met her future husband, Robert Pattinson, on the set of the first Twilight film. The British actor had just finished filming the comedy horror flick, Robocop, in which he plays a character named Alex McNamara. Alex is the son of the late Detroit Police Chief Howard McNamara and his wife, Marjorie. The couple began dating during the last week of filming, and it wasn’t long before they were spotted together at several Hollywood events. They made their first TV appearance as a couple on Jimmy Kimmel Live! in January 2012.

In March 2012, the couple had their first public outing as a couple when they were photographed arriving at Los Angeles International Airport. The following month, they attended the Vanity Fair Oscar Party together. At the time, the press was in a tizzy over the pair’s blossoming romance. It wasn’t long before they were pictured on the red carpet together at the 2012 Golden Globes, Cannes Film Festival, and more.

In September 2012, it was revealed that Robert Pattinson had attended an exclusive private high school in England before graduating from the prestigious Oxford University. According to reports, he was so keen to attend Oxford that he earned a scholarship. The following month, the couple were photographed together for the first time in nearly a year. But by this point, it was already apparent that their romance had endured. The pair were spotted holding hands and cuddling during a romantic summer holiday in Italy in late August 2012. And in the fall of 2012, they were spotted together at the premiere of the new James Bond movie, Spectre. It was a romantic trip organized by Rachel Zoe, who was then Creative Director of Rachel Zoe Designs. Zoe curated the trip with stylist Anna Wintour, and it was clear that these two were determined to bring the romance back. They stayed at Cipriani Hotel in Venice and attended the Venice Film Festival, where they were photographed holding hands. Things were looking up for the young couple.
