Katy Perry put her divorce news behind her on Monday night (16Jul12) by rapping a Will Smith song at a karaoke bar in California.
The pop star, whose marriage to Russell Brand was officially dissolved on Monday, went incognito at the El Galleon venue on Catalina Island and took to the microphone under the name Katherine.
Perry belted out Smith's classic hit Welcome To Miami with a pal, and footage of the night, obtained by TMZ.com, shows the singer finishing the track and then calling out "I love my best friend".
