Style star o' the day: Jordin Sparks.

Fireworks exploded Monday night as the American Idol alum sang the national anthem at the opening ceremony for the 2012 U.S. Open tennis tournament in Queens.

Sparks, 22, showed her curves in a (tennis) white bandage dress that is earning her raves.

Other celebs on hand for the opening included Stanley Tucci and his new wife, Felicity Blunt, and Alec Baldwin and his new wife, Hilaria Thomas.
