Los Angeles (E! Online) – Will Whitney Houston come through and actually perform at Clive Davis' legendary Grammys preparty?

Fingers crossed!

As I first told you in my daily Gossip Guru videoblog on Tuesday, the long-embattled songbird is scheduled to be on the bill when Davis cohosts the annual bash for the first time with NARAS on Feb. 7 at the Beverly Hills Hilton hotel.

Ms. Houston was supposed to perform last year along with fellow superstars like Alicia Keys, Leona Lewis, Wyclef Jean, Josh Groban and Andrea Bocelli, but she canceled because of a death in her family. She did, however, attend the soiree as Davis' date.

And Houston won't be the only welcome-back songstress on the Davis stage...

Jennifer Hudson is another scheduled headliner. This will be the Oscar winner's second performance since her mother, brother and nephew were killed in the fall. As I exclusively reported, Hudson's return to the stage takes places Feb. 1 when she sings the national anthem at the Super Bowl in Tampa, Fla.

Will Houston and Hudson perform together? Probably not, a source tells me, because there "will be so many big voices that night it may be weird just to single them out and have them sing together."

The audience also promises to be star-studded. Among last year's guests were Janet Jackson, Carrie Underwood with then-beau Chace Crawford, Rihanna, Fergie, Pete and Ashlee Simpson-Wentz, Lindsay Lohan, Missy Elliott and Rod Stewart.
