Britney Spears blames herself for her sister's teen pregnancy, it has been claimed.The 'Gimme More' singer's 16-year-old sister Jamie Lynn is pregnant, and Britney, 26, has reportedly told friends she tried to help her sister lead a good life.Britney allegedly told friends: "I've done some pretty dumb stuff and haven't been a good role model. I warned this girl, I really did. She seemed to take my advice." The singer, who divorced husband Kevin Federline this year, has lost custody of her own sons - Sean Preston, two and 15-month-old Jayden James - and is now only permitted supervised court visits with her kids if she passes random drug and alcohol testing.But Britney is still furious that her younger sister has got pregnant by her 19-year-old boyfriend, Casey Aldridge.The 'Toxic' singer reportedly fumed: "I'm really disappointed in her. I told her over and over just to be a kid and let the adult things like sex and drinking and all that wait."I just can't believe she's pregnant. She is way too young to be a mom. She should be having fun and stuff, not having a baby."
