Katy Perry was seen out and about in Los Angeles monday wearing a t-shirt that's an ode to the 80's classic "Girls Just Want To Have Fun" by Cyndi Lauper.
It is reported that Katy performed at Haze at the Aria hotel and casino in Las Vegas over the weekend.
Katy is also doubling as our product placement star of the week, making sure you know what kind of water she is drinking and making sure not to block the label. Congrats Katy on your honor. Maybe girls just want to have fun...and promote?-Dr.FB
