Washington – She’s been slammed from all sides for her underwear-free partying, but Britney Spears now has at least one supporter in porn star Jenna Jameson.

Spears, who was snapped without any panties while partying the night away with new best pal Paris Hilton recently, has been criticized for not covering up the essentials.

Now, it seems that she finally has someone in her corner in the form of Jenna Jameson, who told Star Magazine during the VH1 Big in ’06 Awards at Sony Pictures Studios in Culver City, California, that Britney had every right to flaunt herself, especially after losing all her pregnancy weight.

“More power to her! If you’ve got it, flaunt it! I’ve lived my life like that — and obviously, so has Britney,” the Post Chronicle quoted her, as telling Star.

Britney’s exploits have family, friends and fans extremely worried however, especially with estranged hubby Kevin Federline fighting for custody of the couple’s two sons.

An insider revealed to British paper News of the World that Britney’s mum Lynne is now seething, for she believes that Britney’s antics will come back to bite her, and that the ‘Toxic’ singer might even end up losing her kids.

“She (Lynne) was relieved when her daughter dumped rap husband Kevin Federline. But with Britney going for custody of her two young sons, Lynne fears her antics might influence the judge,” the source said.
