The Oscars 2016 -- After-Party Madness

It's red carpet official!

Gwen Stefani and Blake Shelton walked their first carpet together on Sunday night at Vanity Fair's Oscar after-party, holding hands as they posed for hundreds of photographers.

The "No Doubt" singer looked beautiful in a sheer red and nude paneled dress by Yanina Couture, which she paired with glamorous waves, a Jimmy Choo clutch and a killer red lip. Meanwhile, her beau kept it casual in jeans, a black shirt and a matching jacket.

The couple was snapped with another hot Hollywood duo, Demi Lovato and Wilmer Valderrama, who went with coordinated black ensembles for the star-studded event.

Stefani also performed at the bash, singing hits including "Hollaback Girl" and "Make Me Like You," her latest single about her new beau.

Gwen and Blake like to keep their relationship private, and the mother-of-two usually shies away from talking about the romance.

"So let's talk about Blake," Ellen DeGeneres pressed the singer last week, flashing an adorable photo of the duo on the screen in the background.

"I thought it would be a good idea not to talk about Blake," "The Voice" judge said. "See what would happen."


But DeGeneres wouldn't let the topic go ... and she continued to show photos of the cute couple, including this photo of Stefani sitting on Shelton's lap at Clive Davis' pre-Grammy party earlier this month.

"They didn't have enough chairs at that event?" Ellen joked, causing Gwen to crack up.

Ellen later asked the singer how Shelton "popped the big question" -- check out the clip to see what she said!
