Stepping out to earn a little extra cash, Katy Perry played host at the Samsung Behold II premiere launch party in Hollywood, California on Wednesday night (November 18).

Decked out in a sexy pink ensemble, the "I Kissed A Girl" singer charmed the crowd on hand at Boulevard3 as she did her best to boost interest in the mobile phone company's latest release.

Earlier in the day, Miss Perry concentrated her efforts on keeping her figure in tip-top shape with a trip to the local gym.

She also was busy tweeting away to her friends, professing, "I want to call everyone in my life and tell them I love them. You should too!"
