Kevin

Britney Spears’s current rehab stint has already had one positive outcome — Kevin Federline’s transformation into Super Dad.

A source close to the former back-up dancer says he’s currently put his life on hold while he works overtime to care for his two sons (Sean Preston, 17 months, and 5-month-old Jayden James) and bring his family back together.

“He’s devastated and cries all the time,” a source close to Federline, 28, tells Us. “Kevin wants to get back together with her. He is her biggest supporter.”

The former Mr. Spears may be Mr. Responsible now, but he wasn’t always the picture of perfect fatherdom. In the days before Sean Preston was born, Federline was seen partying and smoking marijuana in L.A. and Las Vegas.

But his experiences with Spears seems to have transformed him. And he might be helping the pop star get back on track, too.

It was at least partially at his urging that Spears entered rehab at the Crossroads Center on the island of Antigua. And when she checked out a day later, Federline and Spears’s mom, Lynne, took the drastic step of taking her children away from her. Federline reportedly told her couldn’t see her sons again until she went to rehab.

It’s unclear how Brit will fare in all this, but one thing is clear: K-Fed is emerging as much more than a punchline for late night TV fodder.
