Radio host Howard Stern really thinks Jake Gyllenhaal screwed up by not marrying Taylor Swift. The "Southpaw" actor went on Stern's Sirius XM show Wednesday and talked about love, marriage and his past relationships, including his short relationship with Swift.

"I feel-and this is me stepping in-you should have married Taylor Swift, and I'll tell you why...What a power couple," Stern told Gyllenhaal. Stern said that he is super attracted to Swift and told the actor that if he was friends with Gyllenhaal at the time the two were dating, he would of told him she was a keeper.

"I would have said, 'Jake, this is The One.' Because to me, nothing is sexier than a woman who can play songs and write," he said.

Gyllenhaal was on "Good Morning America" Monday morning to promote "Southpaw" when the morning show played Swifts song "Bad Blood" in the background as he was introduced.

"First of all, I did not hear that-when I'm doing an interview-when you're up at 5 a.m. and you can't really make sense of words, you're not thinking about the background music that's playing behind you," Gyllenhaal said of being completely unaware of the song playing. Stern joked that the producers were up to no good and played the song on purpose to "make some sort of association" between the two exes.

Gyllenhaal ended the interview by admitting that Swift was a "beautiful girl." Guess there's no bad blood between the two after all these years.
