Katy Perry spent her Friday night hard at work, but managed to fit in a little fun as well!

The “Teenage Dream” singer performed at a MusiCares benefit honoring man of the year Paul McCartney in LA Friday evening. In true Katy fashion (literally), she stood out in quite the interesting headpiece. Afterwards, a source tells Celebuzz that the star hit up Hollywood hotspot Chateau Marmont afterwards.

We all know Katy just officially split from her hubby Russell Brand, so how was she doing?

The source tells us Katy was looking fabulous! Donned in a sexy leather studded jacket, she came into the restaurant area of the hotel on the Sunset Strip pretty late with a large group of friends. Still rocking the blue locks, Katy swept them back in a cute up ‘do while she mingled, but the source told us she did look a “bit bummed.”

Hey, she worked all night, she could have been tired!

We’re glad to see she is doing well post-split.
