Justin Bieber: Victoria's Secret model spurs Harry Styles love triangle - report

Oh, Justin Bieber -- so young, so innocent, so naive. The poor kid hadn't a clue what kind of chaos would erupt from a night of innocent fun with a handful of half-naked lingerie models at the Victoria's Secret Fashion Show.

First his relationship with longtime girlfriend Selena Gomez crumbles after rumors of a post-show dalliance with model Barbara Palvin. Now, Bieber may be on the short list of his One Direction pal, Harry Styles. The UK's Daily Mail reports Styles' former fling, Victoria's Secret model Cara Delevingne, went after Bieber before his performance in a bid to get Harry's attention.

"She's still into Harry and joked she wanted to be pictured with Justin to make him jealous,' says the Mail's source. "She told friends she was going to go for it with Justin, and she did."

Delevingne tweeted a photo of herself in a pink satin robe, cozying up to the Biebs pre-show. The caption reads, "At the @VictoriasSecret show with @justinbieber! So sweet!" Bieber reportedly fell for Cara's flirtatious act hook, line and sinker, and invited her to his after-party.
