Shar Jackson has hired a lawyer to defend herself against claims that she's pregnant with the child of the baby daddy she already shares with Britney Spears, Mr. Kevin Federline. If she sues Star Magazine, which was the first to report the pregnancy, maybe she will no longer have to pimp herself for blingy license plate frames like she did at the MTV Movie Awards gifting suite.

Shar, who denies the mag's claim, says her children are being affected by the rumors, and told TMZ through her rep, "When my kids hear things at school and then ask me if they are getting a new brother or sister, I have to put my foot down."

Based on her vehement denials and a gross offer to hand over an EPT test to Star editor Bonnie Fuller, she's probably telling the truth about not being pregnant. But it was so much more fun to think that she was.
