The 'I Kissed A Girl' singer was pictured out at the star-studded event for celebrity stylist Johnny Wujek's birthday.

Katy Perry was pictured out partying with celebrity guests such as Hayden Christensen and Rachel Bilson at a roller disco themed birthday bash for celebrity stylist Johnny Wujeck in Los Angeles last night (16th July).

The 'Firework' singer donned a flowery outfit and cream shorts complete with a backpack filled with teddy bears as she joined in the festivities at the MoonLight Rollerway in California.

The singer was seen waving her arms around as she hit the dance floor and showed off her best moves for the 90s themed party.

The singer had earlier in the day finalised her divorce from comedian Russell Brand – which they filed at the end of last year.

Katy was all smiles as she partied the night away and lead the guests through a rendition of 'Happy Birthday' for the stylist also helping out putting some of the candles on the cake.

The singer has most recently been seen promoting her new 3D movie Part Of Me and has vowed to go into hiding once she has completed her promotional campaign.

Katy was also recently banned from using her famous spinning bra on stage out of fear she may sustain a neck injury.
