Gigi Hadid is overflowing with confidence after her first Victoria's Secret Fashion Show and she brought some of that vibe to American Music Awards 2015. Not only did she debut her short hair, but she also gave Harry Styles a cold shoulder. Sounds like the night at American Music Awards 2015 is off to a great start for Gigi Hadid.

When the paparazzi were shocked by Gigi's short hair, according to Cosmopolitan, the model said, "You can check back tomorrow to see if I have short hair... there's tricks of the trade."

Sounds like we'll have to check out her Instagram tomorrow morning to see if she did cut her hair into a bob.

But the model didn't just show off hair on the red carpet. She also showed the world that she doesn't have hot feelings for One Direction leader Harry Styles by giving him a curt handshake before hugging the other band member.s

According to Seventeen Magazine, "When E! host Giuliana Rancic asked her if she knew One Direction, she awkwardly shook Harry's hand before greeting Niall Horan, Liam Payne, and Louis Tomlinson all with big hugs. OK, fine, whatever. A little cold, but no biggie, right? Um, but after their quick convo, Harry said, "See ya, sweetheart," and actually rolled his eyes as he walked away."

Seeing how Gigi Hadid just announced her breakup with Joe Jonas, she may be staying far away from musicians. But it might be hard to do that as she is at American Music Awards 2015!

Judging by her Vogue spread with Domhnall Gleeson, it looks like Gigi Hadid is doing very well for herself.

According to Us Weekly, "And now, Gigi Hadid's day job consists of making out with Bill Weasley. In a new, supersteamy shoot for Vogue's December issue, the model jetted off to Portugal and planted a big smooch - in breathtaking designer clothes - on Harry Potter alum Domhnall Gleeson."

The article reports that the 20-year-old model and Joe Jonas "confirmed their split on Nov. 4".

Maybe it was the pressure and joys of starring in Victoria's Secret Fashion Show 2015 that helped Gigi Hadid get rid of her ex boyfriend.

A source according to Daily Mail reported that "'Gigi can't sleep. She's a combination of both excited and incredibly nervous about her forthcoming appearance at Victoria's Secret Fashion Show... 'She's been working out like crazy, sometimes three times a day, and is concerned she's too curvy, so she hasn't been eating too much either."

The added pressure of having a boyfriend probably was too much for the young model.
