Whitney Houston wowed celebrity guests at music mogul Clive Davis’ pre-Grammy party on Saturday when she took the stage with her cousin Dionne Warwick for a duet.
Sir Paul McCartney, Prince, Miley Cyrus, Katy Perry, Usher, Neil Young, John Mayer and Sean ‘Diddy’ Combs were among the A-listers in attendance at Davis’ annual bash.

The crowd was treated to a number of rousing performances, including a duet between Jennifer Hudson and Barry Manilow, a mini-set by R. Kelly and an uncensored version of Cee Lo Green’s Grammy-nominated hit F**k You.

Mumford & Sons, Janelle Monae, Mary J. Blige, Rod Stewart, Leona Lewis and the Kings of Leon also hit the stage, but it was Houston’s finale that dazzled the audience.

The singer, whose performances in recent years have been blighted by bad reviews, proved she was back in fine form as she sang her hits, including I Will Always Love You and It’s Not Right but It’s Okay.

Houston finished off her mini-concert by inviting her legendary relative to join her for a rendition of Warwick’s That’s What Friends Are For.
