Kristen Stewart’s failed relationship with her “Twilight” co-star Robert Pattinson is once again making headlines. Recently, the actress addressed tweets President Donald Trump posted in 2012 about her romance with Pattinson. Ahead of her appearance on “Saturday Night Live” this weekend, where many believed she will address her one-sided feud with POTUS, let’s take a look at the scandal that started it all.

Almost two years after the release of “Twilight” and fans wondering about the status of Stewart and Pattinson’s off-screen relationship, the on-screen love birds were revealed to be a couple in August 2009 after they were photographed kissing at a concert. However, it wasn’t until photos of Stewart cheating on Pattinson that fans finally learned just how deep their connection really was.

In July 2012, paparazzi photos of Stewart kissing her married “Snow White and the Huntsman” director Rupert Sanders began make rounds. A source told US Weekly the pair “seemed like they couldn’t get enough” during their steamy makeup session and spent an afternoon searching for secluded locations in LA.

While fans initially believed the images to be photoshopped, a normally private Stewart confirmed their validity. In a statement, she addressed her feelings on the matter and publicly apologized to Pattinson.

“This momentary indiscretion has jeopardized the most important thing in my life, the person I love and respect the most, Rob. I love him, I love him, I’m so sorry,” Stewart stated. “I’m deeply sorry for the hurt and embarrassment I’ve caused to those close to me and everyone this has affected.”

Sanders, who was married to the mother of his two children, model Liberty Ross, at the time, issued a similar statement saying he was “utterly distraught” by the turn of events.

While fans passionately responded to Stewart’s cheating scandal, her actions didn’t appear to have an adverse affect on her relationship with Pattinson. Rumors began circulating in September that same year that they had reconciled. In October, they seemingly confirmed they were still together after being spotted side-by-side at an LA bar. Their appearances together continued while they promoted the fourth and final “Twilight” film, “Breaking Dawn - Part 2,” in November. Stewart, however, refused to confirm they were still an item.

“Keep ‘em guessing, I always say,” she said during one appearance. And guessing they did. Fans continued to speculate about Robsten until May 2013 when their fate was seemingly solidified after Pattinson was spotted moving out of Stewart’s LA home.

Unfortunately for longtime “Twilight” fans holding out hope for Robsten reunion, both actors have since moved on in their love lives. Pattinson is engaged to singer FKA Twigs (Tahliah Debrett Barnett). The couple has been rumored to be getting married for several months. Meanwhile, Stewart is dating model Stella Maxwell.

It remains to be seen if Stewart, 26, will address her issues with Trump during her “Saturday Night Live” appearance on Feb. 4, but she did recently comment on his former obsession with her. Fans will remember that following the cheating controversy, Trump tweeted to Pattinson that he should “not take back” Stewart for cheating on him “like a dog” and claimed she would do it again. “He can do so much better!” one of Trump’s posts read.

“He was mad at me a couple years. Really obsessed with me a couple years ago,” Stewart told Variety earlier this month. While Stewart said she couldn’t understand why he would speak out on her personal life, she claimed his comments didn’t bother her at the time. However, she did note that Trump will likely respond to her newest statement.

“Hey buddy. What’s up? He’s probably going to tweet about this,” she quipped.
