Katy Perry wore a thong and corset at Billboard Women In Music. The singer's little belly left some wondering if she was pregnant.

The outfit was from Vivienne Westwood's fall-winter 1993-1994 collection. Katy Perry and Orlando Bloom have not commented on the reports that the singer is pregnant with their first child, which is due in the fall. The couple has been dating for about two years, and have a son, Rylin, who was born in January.
