Britney Spears, who started her Saturday visiting with her sons Preston and Jayden, ended the evening at a Russian restaurant for dinner where she met American actor Mel Gibson.
The two, who had landed at the same restaurant with some friends, were once neighbors in an exclusive Malibu community.
"It was exciting to have both of them here together," People mag quoted a source at the restaurant as saying.
"We heard they hit it off and that Britney seemed excited," the source added.
Britney had arrived at the Romanov restaurant wearing jeans, a green top and boots and chewing gum with her friend Victoria.
Gibson, accompanied by a few friends, soon joined them in the restaurant's private dining room, which features a 24-karat gold leaf ceiling, an ornate fireplace and a library stocked with such works as Leo Tolstoy's War and Peace.
The group was said to have dined on filet mignon and Russian specialties, with water and soft drinks for two hours.
An observer remarked that Spears, who left the restaurant for her Studio City home around 8:15pm, "looked happy" and that the meeting seemed to have been a success.
