Lana Del Rey to Jaime King: Happy Birthday!

Lana Del Rey hops into her 1981 Mercedes convertible with Hart of Dixie actress Jaime King outside of a private residence on Tuesday afternoon (April 17) in Beverly Hills, Calif.

Later in the evening, the 25-year-old “Summertime Sadness” singer celebrated pal Jaime‘s birthday during a chic sit-down dinner at the exclusive Soho House in West Hollywood.

Jaime celebrated with her director husband Kyle Newman, Entourage‘s Jerry Ferrara, and actresses Skyler Shaye and Marta Pozzan. Alex Pettyfer was really affectionate with rumored fiancee Riley Keough, who rubbed shoulders with filmmaker Juju Sorelli and musician Eric Lumiere.

“Everyone was having a grand ol’ time eating dinner family-style,” a dinner guest tells JustJared.com. “Jaime was in such a great mood celebrating her birthday with her closest friends.”

All of the dinner guests sang Jaime “Happy Birthday” before she blew out a candle atop a plate full of gooey chocolate chip cookies. Everyone then devoured three bowls full of homemade whipped cream, meringue, and mixed berries.

Jaime‘s actual birthday is on April 23 – she turns 33. Happy birthday, Jammers!

FYI: Jaime is wearing a Jason Wu for Target dress.
