Bill & Tom Kaulitz: Bootsy Bellows Boys!

Tokio Hotel rockers Bill and Tom Kaulitz leave Bootsy Bellows after a night out together on Tuesday (August 15) in West Hollywood, Calif.

The brothers kept low profiles as they stepped out of the swank Hollywood hotspot, where British boy band The Wanted gave a surprise performance the same evening!

Last week, the boys of Tokio Hotel partied with Aerosmith after enjoying their concert! Bill and Tom hit up the after concert party and hung out with Johnny Depp and other A-listers later in the evening.
