Katy Perry: Girls Just Wanna Have Fun!

Katy Perry heads to the gym and then stops by Urth Cafe to pick up lunch in West Hollywood on Monday (January 25).

The recently engaged 25-year-old “I Kissed A Girl” singer wore a Wildfox Couture ‘Girls Just Wanna Have Fun’ t-shirt to her workout.

Katy is back home after hosting a party at Haze Nightclub at the Aria Resort Hotel Casino in Las Vegas over the weekend.
