Taylor Swift And John Mayer's Awkward L.A. Run-In

Sources say the former pair tried to avoid each other out at a West Hollywood bar after his Rolling Stone confession.

John Mayer and Taylor Swift had the misfortune of being the same place at the same time on Tuesday night in Los Angeles. Making things all the more awkward was the fact that earlier that day, Rolling Stone published an interview with Mayer in which he admitted that Swift left him "really humiliated" when she released her track, "Dear John."

Swift and Mayer had their run-in at West Hollywood hotspot Tower Bar. According to the New York Post, Swift walked into the hangout and noticed Mayer, who was there with a friend. "Taylor very visibly — in front of the entire restaurant — demanded to be moved to the other side," the eyewitness said. "The bar's usually an oasis of calm and privacy for celebrities and power players, but this was drama central." But according to a Swift source who spoke with Gossip Cop, there was no nasty confrontation and while the singer was at the bar, it's not even confirmed whether they saw each other.

Meanwhile sources tell UsMagazine.com that she's still reeling from his interview. "I can't believe he is trying to play the victim!" the source said of Mayer, who reportedly dated Swift in 2009, while they were working on music together.

"John was a player and treated her like s--t," another insider says. "He looked at her as a conquest. Taylor is going to think even less of him now!"

While he may feel that using their relationship as fodder for her Speak Now ballad was "cheap songwriting," when MTV News spoke to Mayer in 2009, he was singing a different, more pleasant, tune about the pop star.

"I woke up with the song in my head called 'Half of My Heart,' " he explained, noting that the Battle Studies duet came about via Twitter messages they shared. "And the idea is that it's this real sort of updated — not that it needs to be updated — sort of Tom Petty, Fleetwood Mac, Stevie Nicks thing.

"I thought, 'Well, if this is going to be my love letter to that style of music, who's going to be the Stevie Nicks in this equation?' " he recalled. "And I thought, 'This Taylor Swift girl is going to be around for a long time.'"

So, what is making Mayer so angry these days? Well, on her song, she sings, "Dear John/ I see it all now that you're gone/ Don't you think I was too young/ To be messed with/ The girl in the dress/ Cried the whole way home/ I should've known."

"I never got an email. I never got a phone call," he said in the new interview, out this week. "I was really caught off-guard, and it really humiliated me at a time when I'd already been dressed down. I mean, how would you feel if, at the lowest you've ever been, someone kicked you even lower?"
