panty-challenged singer, Britney Spears slammed?

Gossips are slamming panty-challenged singer, Britney Spears after she was seen carrying a glass of wine to her car..

The singer was spotted carrying a glass of wine to her car after a November 28 dinner at Dan Tana’s in West Hollywood. Though she gave the wine to an assistant before climbing behind the wheel, the singer then drove herself to meet pals at Hyde.

Spears' partying since breaking up with husband Kevin Federline could jeopardize her petition for sole custody of sons Sean, 15 months, and Jayden, 3 months.

"Britney is out of control, and Kevin is having a quiet dinner discussing strategy," a rep for Federline's lawyer told Us on November 30.

And a source close to Kevin Federline -- who, like Spears, 25, is requesting sole custody of the children – ominously suggests that the California Department of Child and Family Services could get involved, saying, “They’re not watching Britney, but all it takes is one phone call and they will be. It doesn’t help that she’s leaving clubs with wine glasses.�

Meanwhile, a spokesman for a lawyer repesenting Kevin Federline issued a press release yesterday to promote a dinner "event" featuring Kevin Federline eating reports TMZ.

Several media outlets were invited to cover the "event."

The press release also said that Federline has forgone his "signature gold chains that he wore around his neck" in place of "a fabulous well-stated sport jacket with open collar shirt."
