Bosworth and Skarsgård, who costarred in the movie Straw Dogs, reportedly dated from 2009 to 2011, before breaking it off, according to People. Despite the breakup, they still apparently remained on good terms, both professionally and personally.
"Alex is so kind and so dedicated and so incredibly professional," Bosworth said during the Straw Dogs press tour. "He's got this rare, wonderful control and stillness that you notice in a lot of old movie stars. He looks you in the eye. I feel incredibly lucky to have had that type of man on this movie."
Skarsgård had similarly kind words to say about Bosworth. "Kate is such a great actress, and she's so much more than a good-looking Hollywood starlet. We were just really good friends at the time," he told BlackBook.
In 2018, the exes bumped into each other at the Met Gala and, according to Us Weekly, chatted briefly and even posed for pictures together.
