Britney Spears pays tribute to the late, great Whitney Houston.

Britney Spears has been pretty busy lately, what with dressing up like Cleopatra and sauntering down empty hotel hallways in her "Fantasy Twist" fragrance TV ad. But the "X Factor" judge recently took some time out of her packed schedule to pay tribute to the late, great (perhaps the greatest of them all) Whitney Houston.

Billed as the "We Will Always Love You: A Grammy Salute To Whitney Houston," Britney joined celebs like Halle Berry, Jennifer Hudson, Usher, Celine Dion and others at the Staples Center to tape a one-hour tribute to Whitney honoring her life and legacy. Naturally, Britney was beyond thrilled to be paying tribute to Whitney and tweeted about it to all her fans: "I am both honored and humbled to take part in the GRAMMY salute to Whitney Houston on Thursday... She'll always be 1 of my heroes!" Ours, too, Brit. Ours, too. We're looking forward to watching the show, which airs Nov. 16 at 10 p.m. ET/PT. So set your DVRs now!
