Rihanna @ TRL

Rihanna drops by TRL on Thursday (taped Tuesday) and chats up Josh Hartnett, Laura Bell Bundy (Legally Blonde on Broadway), and members of pop punk group Paramore — lead vocalist Hayley Williams, lead guitarist Josh Farro, bassist Jeremy Davis and drummer Zac Farro.

Hartnett, 29, promoted his new film 30 Days of Night, which opens nationwide Oct. 19th. Bundy promoted the hit musical premiere of Legally Blonde on MTV, which airs this Saturday, October 12 at 1PM EST.

Favorite photo of the bunch: The giant-size Rihanna standing a foot taller than pint-size Paramore singer Hayley.
