Katy Perry leaving Kay West Hotel with a group of friends, London, England - 27.02.09

The I Kissed A Girl hitmaker split from the Gym Class Heroes frontman earlier this year (09) before being linked to Paris Hilton's ex-Benji Madden.

But she's now found love with fellow musician Groban, according to PerezHilton.com.

A source close to the pair tells the website, "They've been trying to keep it very low profile."
