Singer Jessica Simpson will be following in her idol Angelina Jolie's footsteps later this month (MAR06), when she lobbies members of Congress on behalf of a children's charity. The star will head to Washington, DC to speak with lawmakers about Operation Smile, an organisation that provides surgery for children with facial abnormalities. Simpson visited Africa last year (05) as a guest of the charity group. A source close to the organisation confirms, "She's in the phase of her life now where she wants to use her celebrity for good. "She's flying in on her own dime. This is her Angelina moment." Meanwhile the singer-turned-actress has hinted she is ready to abandon her music career for good, despite being contracted to release another three records. The With You hitmaker made her acting debut in last year's (05) The Dukes Of Hazzard and is now keen to pursue a Hollywood career. However, Sony music insists the starlet is contracted for at least another three discs.

Simpson says, "Music will always be my passion, but I don't have to do it professionally. It's just not really about that for me anymore.

"I feel like I don't have to look at it as a career. I can just rest in it and just be."
