It seems Christina Aguilera made such an impression singing the national anthem at Game 6 of the Lakers vs. Celtics NBA Finals on Tuesday that the basketball league brought her back last night to do it all over again for the nail-biting Game 7, in which the Lakers took the title with a 83-79 win.

Singing an encore of her soulful interpretation of the patriotic tune, Aguilera went equally sexy this time 'round, trading in the black strapless getup and leopard heels that she wore for Game 6 for a skin-tight color-block Hervé Léger bandage dress, black patent Christian Louboutin "Bianca" pumps ($735), and a chunky cross necklace.

The cleavage-baring look was perfectly complemented by a messy bun, crimson lips, and black winged cat eyes, which the pop star also donned courtside when she joined her husband to watch the game after slipping into something more comfortable -- a pair of tight frosted jeans and a baggy white shirt.

We're just thankful she left the latex at home.
