Rapper Wiz Khalifa got caught taking a whiz.
Authorities boasted of nabbing the rapper during his brief visit to Pittsburgh.
He allegedly relieved himself behind a bar early Saturday, resulting in a public urination ticket.
Kalifa, whose legal name is Cameron Jibril Thomaz, was given a 2:30 a.m. ticket behind The Flats in the city's South Side, according to the Pittsburgh Bureau of Police.
Hours before nature called, Khalifa had performed at Pitt's Midnight Madness.
The citation came hours before Khalifa performed alongside Lil Wayne in Philadelphia on Saturday night.
