Inside the Exclusive Daily Mail Celeb-Studded Yacht Party at Cannes Lions

Movie stars, models, socialites and singers were all in attendance Wednesday.

Celebs were in town for the Cannes Lions International Festival of Creativity.

"I'm very excited to be here. This is great," said Lana Parilla, the evil queen from ABC's "Once Upon A Time."

Founder of TheDishh.com and socialite Jonathan Cheban was also at the soiree, saying, "I wouldn't miss it for the world, and it's in Cannes."

"Me and Rob are so excited about the new baby," she told ABC News, adding that the newly-engaged couple will likely be planning their wedding next year.

"The Daily Mail really treated us to a lovely evening," Stewart said. "It's spectacular."

The "Want To Want Me" singer also gave the party his stamp of approval.

"We had the biggest party of the night right here," Derulo said. "I can't wait until the next time. We gotta do this again."
