The lovebirds happily posed for photographs at the event, Camille brought the glam in a lace white romper by Elie Saab while David looked suave in a classic navy suit.
"Camille is very happy. They met through mutual friends at a party. He's lovely," a source tells E! News of their relationship.
The sources reveals that Camille and David started dating several months ago, and that he has met her two children, 15-year-old Mason Grammer and Jude Grammer, 12. David also accompanied Camille on a recent ski trip to the Swiss Alps, and was pictured in a sweet photo collage from the adventure shared by Camille's Instagram page.
"Had a great time in Gstaad," Grammer captioned the photo. "Met some fabulous people from several different countries. Great stories, food and skiing. Thank you JP for hosting us. Interesting conversations with people from London to Saudi Arabia. Looking forward to going back next year"
The source adds, "Camille is in a really good place."
