It was all about mother-child bonding with the Spears family this weekend.

While troubled singer BRITNEY enjoyed her first overnight stay with sons SEAN PRESTON, two and JAYDEN JAMES, one, her own mum, LYNNE SPEARS came along for the ride.

The duo played happy families (if only for one day) as they enjoying some shopping at the True Religion warehouse and Pottery Barn on Friday before enjoying a "girls dinner" of salad, sushi rolls, and fish at Bond St. restaurant with two of Britney's pals.

"Britney walked in with a big smile and introduced her mom to the staff," says an observer. "She looked gorgeous, and I have never seen her in a better mood. She was laughing the whole time she was here. Britney seemed to have the best time hanging out with her mom and friends."

While Brit hung out with Mama Spears the family patriarch JAMIE, who is currently Britney's legal conservator, spent the weekend at his new house in Santa Monica.
