Katy Perry recently covered Lady Gaga's new song "Born This Way" at a concert in Paris.
Lady Gaga, 24, released the track, which is currently No. 1 on the Billboard Hot 100 singles chart, in early February and premiered its music video on February 28.
The clip features the pop singer with an eyeball on her chin, fake horns and pointy shoulders and is meant to mark "the birth of a new race" that bears no prejudice.
Perry, 26, is currently on her "California Dreams" tour and will perform a series of concerts in the United States and Canada, starting in June (see tour dates).
"@rustyrockets don't be a drag just be a queen!" Perry wrote to her husband Russell Brand on her Twitter page on Monday, the day of her Paris concert, quoting a line from "Born This Way."
Perry then said: "Oh Paris... Can I see you again tomorrow or would that make me slutty?"
