Katy Perry was all smiles on Thursday, spotted on the Santa Barbara set of a photo shoot for Adidas. 

Perry's now sporting a new blue hairdo, but she was sans wedding ring.

Russell Brand was spotted Friday for the first time since the divorce news broke, arriving at LAX with a throng of paparazzi waiting for him.

We're told the couple is on good terms, despite the divorce.
