I don't think Lynne Spears is all that bad. She did snatch Britney's ass up when she married that guy in Vegas. Plus, didn't she try to convince Brit not to marry Kevin? And also to make sure to sign a pre-nup?
Britney never really seemed to get into trouble when she was a minor, so Lynne must have been doing an okay job. Once Brit got out on her own is when all the shit hit the fan. You can't always blame the parents. Especially once the kid is no longer a kid.
Not saying she's perfect by any means, but it does seem that she's tried many times to talk some sense into Britney-- it's not her fault that her daughter nevers wants to listen.
Then again, I guess all the stage mothers look fabulous compared to Dina Lohan.
