After nine months of dating, the two stars have broken up, two sources confirmed to E! News. According to one insider, the breakup was "amicable and recent."
"It wasn't dramatic or anything like that," a second source close to the Captain America: Civil War star told E! News.
Though the two were photographed toasting to 2017 on New Year's Day, the Avengers actor headed off to Super Bowl 51 a month later with friend and co-star Jeremy Renner. Meanwhile, in hindsight, Slate's notable absence from the game was a sign of trouble in paradise.
