Kevin FederlineKevin Federline is reportedly worried but glad that ex-wife Britney Spears is finally getting treatment for her as-yet undiagnosed mental condition.

Kevin is said to be in regular communication with his former mother-in-law Lynne Spears so knew about the intervention plans in advance but was still glad when the plan was pulled off.

A source close to Kevin told People magazine: “He’s worried. … He doesn’t even know what’s going to happen next.”

“[He] doesn’t want her to get out [of hospital] until she’s made progress. This is obviously going to help her in the end – later, much later.”

“Kevin legitimately wants Britney to get better. He wants her to be in their sons’ lives. He wants them to have a loving relationship. He wants her to get healthy so she can be the mother they need and deserve.”
