Gabriel Aubry and Halle Berry
and beau Gabriel Aubry left baby Nahla Ariela at home to celebrate Berry's 42nd birthday at a star-studded Robin Thicke concert Thursday.
The Los Angeles House of Blues was packed with celebs (from
), but all eyes were on the beaming Berry as the evening culminated with Thicke delivering an a cappella version of "Happy Birthday" to the smiling star.
Berry, sipping a glass of chardonnay, looked stunning in a black cocktail dress as she and Aubry hung out with gal pals – and heavy security – at her balcony table across from Spears.
Around 11 p.m., Thicke stopped the band and announced that there was a "very special lady in the audience tonight, who's celebrating a birthday." The crooner then busted out "Happy Birthday." He finished the song imploring the crowd to, "Give it up for Halle Berry, everybody!"
The sold-out audience applauded madly as flashbulbs flashed. The lights where quickly dimmed, as Thicke moved into his hit, "Angels."
At the end of the evening, Thicke's wife Paula Patton (sitting with an energy-filled P-Diddy and his buddies who, says an onlooker, "were going crazy!") gave Berry a big hug before Berry, leading her boy Gabriel by the hand, was led to a waiting black Escalade.
