Soul music legends Gladys Knight and Patti LaBelle wowed fans on Sunday night’s episode of Verzuz.

Although the premise of the show pits two performers head to head, Knight and LaBelle shined with nothing but love and respect for each other.

“We are so happy to be together,” LaBelle said at the start of the show. “We’ve been together for many, many, many years.”

This week’s stars battled with hits like Knight’s “Midnight Train to Georgia” and “License To Kill,” and LaBelle brought hits including “Lady Marmalade” and “If You Ask Me To,” the latter of which she reminded the audience she originated. “Céline did this after I did,” she said, referencing Céline Dion‘s version of the song.

The performers ended the live stream by bringing out a fellow living legend, Dionne Warwick.

“I wanna tell y’all, y’all have been singing your faces off out here,” Warwick said. “I’ve been loving every second, I have. It’s been wonderful.”

She performed “That’s What Friends Are For,” before the trio sang “Superwoman” to close the show.

After the show, Knight tweeted, “Thank you all for joining us. It was truly a blessing to be with you!”

Verzuz was started by Timbaland and Swizz Beats in March, and has featured other artists in the past like Rick Ross and 2 Chainz, DMX and Snoop Dogg and Alicia Keys and John Legend. The show began on Instagram Live, but has grown to Apple Music and YouTube. The production value has also gotten better and the series has quickly grown in popularity, going from two stars video chatting each other, to full on performances in a dedicated space, like viewers saw on Sunday night.
