A couple of California girls were fine, fresh, and fierce at a post-Grammys party!

Selena Gomez proved that the constant press of her ex-boyfriend Justin Bieber on SNL this weekend couldn't distract her from having a ball with pal Katy Perry after the Grammys on February 10, according to People.

Selena arrived to the Warner Music Group after-party at the Chateau Marmont around 1 a.m.

There, she met up with Katy Perry and John Mayer, along with Girls star Allison Williams, who was Katy's date to the Grammy ceremony.

Katy says she had fun with Allison as her date, but there's no doubt she would have preferred to have John by her side the entire night. 

"He's a better date, no matter what time of the day!" she admits.

The group stayed at the Chateau until around 2:30 a.m., at which point they left for a private party.

Katy has a song about getting crazy on Friday nights, but it appears she has no problems letting loose on a Sunday night, too!
