Christina Aguilera, Faith Hill and gospel group Take 6 have joined the ever-growing list of performers set for this year's Grammys, the awards show announced Monday.

Aguilera, who won last year's Best New Artist award, is up for Best Female Pop Vocal Performance for "What a Girl Wants" and for Best Latin Pop Album for Mi Reflejo. Country crossover star Hill is up for Best Country Album for Breathe, Best Female Country Performance for that album's title track, and Best Country Collaboration with Vocals, the latter for her duet with husband Tim McGraw on "Let's Make Love."

Seven-time Grammy winners Take 6, who released a career-retrospective live set in 2000, aren't up for any awards this year. They'll perform with jazz vocalist Nnenna Freelon, who is up for Best Jazz Vocal Album for Soulcall and Best Instrumental Arrangement Accompanying a Vocalist for "Button Up Your Overcoat."

Also announced Monday were the additions to the presenters' roster of Toni Braxton and Aerosmith leaders Steven Tyler and Joe Perry. Previously announced performers for the February 21 telecast include Destiny's Child, U2, Madonna and 'NSYNC (see "'NSYNC, Destiny's Child To Perform At Grammys").
