On Saturday night, Billboard held its official BBMA pre-party at Tryst at the Wynn hotel, sponsored by Samsung, Buffalo Jeans, Chevrolet and Las Vegas Convention and Visitors Authority.

Executives from all of those companies and many others were in the house to hear a hot DJ set from Rashida and a set from Andy Allo, winner of Billboard's Next Big Diva contest – and none other than Prince, who has been a sort of mentor to Allo and came by to check out her set shortly after sound-checking for his performance at the Billboard Music Awards.

Allo, who played with Prince’s band on two tours in 2011 before focusing on her own career, performed a rousing set of originals spiced up with a couple of surprise covers: The Knack’s “My Sharona” and Parliament’s “Tear the Roof Off the Sucker.” She’s a stellar singer and a mean guitarist, and was backed by a tight six-piece band in matching outfits that had a sort of big-fringe motif. Prince’s manager Julia Ramadan and his current band were in the house showing their support as well. (Prince allowed no photos.)
