Gwen Stefani and Blake Shelton All Loved Up at Clive Davis’ Pre-Grammy Bash, Plus all the Red Carpet, Backstage and Show Photos

It was a star-studded and love-filled evening!

Music royalty and a bevy of other celebrities attended last night’s (Feb. 14, 2016) Clive Davis’ pre-Grammys party at the Beverly Hilton Hotel in Los Angeles, California.

Lovebirds Gwen Stefani and Blake Shelton were seemingly enjoying Valentine’s Day with Stefani perched on Shelton’s lap. The duo seemed quite smitten with one another, exchanging kisses throughout the evening.

Some of the other stars attending the event included Chrissy Teigen and John Legend, Avril Lavigne (with Chad Kroeger) , Barry Manilow, Caitlyn Jenner, Christina Aguilera, Adam Lambert and both Harry Styles and his former bandmate Zayn Malik, formerly of One Direction.

Manilow made a surprise return to the stage for Clive Davis’ pre-Grammys party in L.A. Sunday night (Feb. 14) just days after being hospitalized.

“I’m really glad to be here. What a week!,” the 72-year-old singer said after the performance. “This is the 40th anniversary of the release of “Mandy” — and the beginning of this beautiful party” (referring to Davis’ pre-Grammy gala).

Lavigne and Kroeger reunited on the red carpet and were spotted getting cozy at a pre-Grammy party Sunday night – five months after splitting following two years of marriage. Have they reunited? The singer posted this photo to her Instagram account.

Grammy Party ….. Feeling great. Lovely night.

Chrissy Teigen and John Legend looked like they were having a blast during the event. The duo took a number of selfies during the night and were seen mingling with the other A-listers in attendance.

The supermodel wore a figure-hugging green dress by Galvan that showed off her growing baby bump, and sparkled with rocking Le Vian diamond rings, a Djula diamond ring and an Antonini diamond ring.

Guests enjoy performances by such artists as Beck, Dave Grohl, Adam Lambert, Jack Antonoff, Melissa Etheridge, Fetty Wap, Tori Kelly, Audra Day, Ellie King and more.

Four years ago this week Whitney Houston died, tragically, on the night of Davis’ 2012 pre-Grammys party. To pay tribute to the “greatest contemporary singer of all time,” the party screened the only previously-taped performance of the night: Houston doing her hit The Greatest Love of All during Arista’s 15th anniversary party.
