Katy Perry stole her support act Natalia Kills' clothes while she was warming up for the star at a gig St Louis over the weekend.
The singer jokingly revealed details of her plan on Twitter, before Natalia Kills later confirmed that Perry had gone through with it.
Perry wrote: “Tonight we welcome Natalia Kills to the California Dreams tour tonight!!! When she's on stage I'ma steal her amazing clothes! CHI-TOWN!”
Later, Natalia Kills said: “...just got off stage at the Katy Perry show but I can't find any of my clothes. Wtf!”
Meanwhile, Natalia Kills is set to release her debut album 'Perfectionist' on September 5. The record includes the singer's new will.i.am-featuring single 'Free' and a collaboration with Akon.
Natalia Kills was originally born in Bradford to Uruguayan and Jamaican parents, but moved to Los Angeles in 2008, where she was signed by Black Eyed Peas star will.i.am.
