What, no grille? Faith Hill was rocking a very unexpected accessory at the Grammy Awards at the Staples Center in L.A. Sunday, Feb. 10: Braces! Clad in a black J. Mendel gown (plus Lorraine Schwartz jewelry, Tom Ford shoes and a Bottega Veneta clutch) and standing beside husband Tim McGraw, the 45-year-old country singer sported clear orthodontic gear on her famous smile.

 Hill first debuted the braces at the Country Music Awards. "I had braces as a kid. I forgot to wear my retainer," she recently explained to radio station KNIX.

"Kids, wear your retainer!" the presenter joked. She and McGraw, also 45, are parents to daughters Gracie, 15, Maggie, 14, and Audrey, 11. Inside the bash, the country couple hung out with Keith Urban and wife Nicole Kidman.
