She was breezy talking to E! on the red carpet, dressed in very low cut black gown. Her birthday's coming up, and she said she'll "be in London, doing the Ritz." 7:23 p.m. ET: Nicki Minaj has arrived with ... a bishop. She's wearing a large, red cape type thing. With a hood. Gaga, eat your heart out. 7:10 p.m. ET: Second (maybe) to Hudson's Houston tribute, Adele's performance is the most anticipated moment of the Grammys. E! heard the singer, fresh from vocal chord surgery, during rehearsals. They said she sounded spectacular. 6:41 p.m. ET: On the E! red carpet, Kelly Rowland reiterated what many have said leading up to tonight's ceremony: "It's a very somber tone, tonight at the Grammys. We've lost our hero. 6:39 p.m. ET: R&B singer Kelly Price was the last person to sing with Houston. They did an imprompteau duet at a Thursday pre-Grammy party in Hollywood. "I wasn't expecting her to sing, I wasn't going to ask her to do that," Price told E!"s Ryan Seacrest. She walked up on the stage and said give me the mike. So I gave her the mike. And I walked up on the stage and sang with her. On Houston's death, Price said, "In my heart, I was praying it was an Internet hoax. ... To realize that it wasn't, I don't even know how to explain it." 6:38 p.m. ET: It's going to be a somber celebration at the Grammys tonight. One day after Whitney Houston's sudden and untimely death, stars are hitting the red carpet and no one can stop talking about their memories of her. She'll also be a big part of tonight's show - Jennifer Hudson is slated to perform Houston's 1992 hit "I Will Always Love You." PHOTOS: The Grammy Red Carpet
