Guess Which Celeb Got Caught Kissing Jake Gyllenhaal?

Jake Gyllenhaal fanned flames that he’s dating Ruth Wilson after a workout Saturday, according to an E! source. The actor, who starred in the Broadway show Constellations with Wilson this past winter, waited for her in the lobby of Barry’s Bootcamp while she showered up. “Ruth and Jake left separately,” said the eyewitness source. “But while he waited, he was chatting with the people she ended up leaving with.” Apparently Gyllenhaal was friendly to the folks headed out of class — but most friendly with Wilson. “When Ruth came out, they kissed each other goodbye before parting ways. It was more than a peck on the lips between friends. This was a kiss that said, ‘We’re dating.’” Relationship rumors have swirled around the pair since last December, when they were seen leaving dinner together, looking cozy. Both have denied that they’re involved: The Affair actress has even gone so far as to say that Gyllenhaal is like an “adorable, good guy” who has become like a brother, according to E! Ouch. Even if they’re not romantically involved, getting relegated to the bro-zone always stings a little bit. But, we’re still not sure that Wilson is copping to the truth here. The actors look awfully close for siblings, even by Gyllenhaal family standards. And, who could blame them for taking the smooching offstage when they did so much of it in their hit show? Guess we’ll just have to wait and see...
