Man. Mark Vincent Kaplan is dishing out subpoenas faster than Britney Spears slings the poon when Criss Angel rolls up trying to tap that!
Kevin Federline's lawyer has struck again, delivering a summons to the rehab facility attended by Brit.
Kaplan confirms that Promises Treatment Center was indeed served Saturday morning, saying, "An executive administrator from Promises was served with a subpoena."
This is the fourth subpoena doled out by Team FedEx in the custody battle.
Earlier in the week, Spears's former assistant Shannon Funk, bodyguard Daimon Shippen and "cousin" Alli Sims were all hit with legal papers.
"Kevin Federline and his attorneys, Mark Vincent Kaplan, and James Simon are on a mission," says a source close to the proceedings. "They are pursuing all relevant evidence."
A spokesperson from Promises refused to comment, saying: "This is a confidential facility and we cannot comment."
The pop star spent a month at Promises and was released on March 21. Her manager at the time said she was "successfully" released.
Meanwhile, as sons Sean Preston and Jayden James spent the weekend with Spears (God help them), Kevin partied like a mofo until the wee hours of the morning.
Having kept a low profile for the most part lately, Kevin Federline hit the Venetian's Tao Nightclub in Las Vegas Friday night - with a party of 25.
"He was drinking straight from vodka and Jagermeister bottles," an onlooker said. "I didn't see him with a drink in his hand that much, but he drank out of the bottles a few times."
Nice. Federline and his crew arrived at the club around 11:30 p.m. and had dinner at Tao's Loft before retreating to the club at 1 a.m., says a source.
There, Federline, dressed in jeans and a yellow polo shirt, started the party with bottles of Jack Daniels, Grey Goose and Jagermeister.
Stationed at his table, K-Fed chatted with a few of the girls surrounding him, and later migrated to the table full of women adjacent to his.
"He was grinding up on a few of the girls," the source said. "He had a flashlight and was shining it on some of the girls around him."
Thoughout the night, Federline flashed his gold necklace to the deejay, DJ Reach, and even held up a cigarette lighter when the deejay played Jay-Z's "Big Pimpin'."
Smiling, grinding, hittin' the bottle and smoking like a chimney throughout the night, the always classy Kevin Federline finally left the club around 4 a.m.
