Ruth Wilson says Jake Gyllenhaal is "adorable."
The 33-year-old actress, who was reportedly "all over" the 'Nightcrawler' star in Los Angeles earlier this month, admits she trusts the 34-year-old heartthrob "implicitly," but claims they are "like brother and sister."
Asked about her 'Constellations' co-star, the 'Affair' beauty told Net-a-Porter's The Edit magazine: "He's adorable, a really good guy. We've become like brother and sister a little bit. We spend so much time together. We trust that even if we have a little [disagreement]--which is going to happen because we're in a tense environment that demands a lot from us--we'll make up and we'll be fine. I trust him implicitly."
A source previously claimed the duo were very affectionate after Ruth picked up the Best Actress in a Television Series (Drama) award at the Golden Globes.
The insider said: "Ruth and Jake were all over each other and didn't seem to mind who saw them.
"They were holding hands and shared a little kiss, it was sweet."
Ruth and Jake were also spotted "kissing several times" while dining in New York in December.
The 'Brokeback Mountain' actor split from Sports Illustrated model Alyssa Miller in December 2013.
