Britney Spears' former rehab facility subpoenaed in custody battle

Britney Spears' former rehabilitation facility, Promises Treatment Center, is the latest to be subpoenaed in the custody battle between Britney, 25, and her ex-husband Kevin Federline, 29.

According to a source familiar with the proceedings, Promises Treatment Center was served with a subpoena Saturday morning. This is the fourth subpoena handed out by Kevin's legal team. Earlier in the week, Britney's former assistant Shannon Funk, bodyguard Daimon Shippen, and pal Alli Sims were all served with legal papers.

A source close to the case said,

Kevin and his attorneys Mark Vincent Kaplan and James Simon are on a mission. They are pursuing all relevant evidence from every potential source and every available witness.

A spokesperson from Promises refused to comment, saying,

This is a confidential facility and we cannot comment.

Britney spent a month at Promises and was released on March 21. Her manager at the time said she was 'successfully' released.
According to Pepperdine University Law Professor Steven M. Cron, the Kevin's camp is clearly seeing how Britney took to the Promises stint.

Strategically I don't think they are concerned with the treatment, but how she responded to that treatment. Specifically, if she participated as she was supposed to. Did she have a positive attitude, did she complete it successfully. Or was she a screw up?

According to Popcrunch Kevin Federline has tracked down a European brunette he claims banged his ex-wife, with his permission, following a naughty night out at a gay bar in Copenhagen in 2004. K-Fed has commissioned the sultry lesbian to testify in his bid for custody of Brit’s boys in Los Angeles Superior Court on September 17th. source
