The notorious big sister has spoken out regarding the pregnancy of her now equally controversial younger sister. According to People, Britney Spears recently told a friend, “I’m really disappointed in her [Jamie Lynn]. I just can’t believe she’s pregnant. She is way too young to be a mum. She should be having fun and stuff, not having a baby.” According to the pop princess, she repeatedly warned Jamie Lynn about the fast life. Britney Spears said, “I warned this girl, I really did. I told her over and over just to be a kid and let the adult things like sex and drinking and all that wait.” The Blackout singer also said she had several heart-to-heart talks with Jamie Lynn over the last year and “she seemed to take my advice”. Well, apparently not big sister! Also, Britney Spears is not shy to admit that she has not been exactly a good role model to her. She says, “I’ve done some pretty dumb stuff and haven’t been a good role model.” In fairness to Britney, she got pregnant AFTER getting married. Is that a good role model or not?? =)
