Last night in L.A., celebs were on hand for the We Will Always Love You: A Grammy Salute to Whitney Houstonevent. And J-Hud stole the show by channeling one of Whitney's 80's looks as she performed in honor of the late star. And we're sure she did it right.

She rocked the stage with a medley of "I'm Every Woman," "How Will I Know" and "I Wanna Dance With Somebody".

Jenny also posed backstage with Britney Spears who was on hand, and Brit said Whitney's "I Have Nothing" started her own music career.

Whitney's daughter Bobbi Kristina arrived in a red Herve Leger dress and strappy black sandals. And with her new fiance, Nick Gordon, on her arm.

Krissy switched out her sapphire engagement ring for her mom's diamond rings for the occasion. And the twosome held hands and got extra cuddly while getting teary eyed during the show:

Meanwhile, Halle Berry took the stage to salute Whitney in the show's introduction:

Usher performed ''I Believe In you and me''.

Cece Winans performed with Bebe ''Count on me''.
