Katy Perry, wearing a sweet purple frock, launched her debut scent Purr today at Selfridges department store in London.

The fragrance, which comes in a kitty-cat shaped bottle (of course) wasn't named after Perry's kat, Kitty Purry. "I’m a very lyrical-based person, and the whole ‘purr’ thing kept coming back," she said of the name. "Perfume, perfect, even Perry if you say it a certain way. It just seemed logical."

And Katy had another thing to be celebrating today.

Glee's version of Perry's single "Teenage Dream" may set a record for the biggest one-week download sales of Glee song ever.

Billboard reports that the track, sung by the rival all-boys Glee club called "The Warblers", could sell as many as 175,000 copies by Sunday (it was released on Tuesday), which would make it only the second top ten single ever to come out of the hit series. The first was "Don't Stop Believin'" which hit number four on the Billboard's hot 100 with a total of 177,000 copies in its first week.

Congrats, Katy!
