Lynne: Jamie Has Been a Rock for Britney

Britney Spears has been on major lock down lately, but this is the most sane she's been for over a year, and we have her dad Jamie to thank for it.

Brit's mom Lynne Spears has been praising her ex-hubby for stepping up to the plate and getting things under control again.

"Jamie had to change his whole routine. Lynne sings his praises. He has been such a rock. He has stepped up to the plate," a family friend tells People.

"He's gathered a team of reputable people who are around [Britney] now. She's not well, but for the first time in a long time she has people around her who really care about her."

Brit's definitely been less of a train wreck since daddy Spears came into town, but how long can he keep her under his control? He's already moved into her house and rearranged his entire life.
