K-Fed leaves Busby’s in WeHo at 2 am in a friend’s yellow Lambo.

Sweet ride, Kevin. I need more friends with Lamborghinis. Anyone have a Lamborghini and want to be my friend? I don’t take up too much space, and if you put a few Red Bulls into me I tend to let you put a little something else into me. If you have a Lamborghini, that is.

I wonder who had the kids.

He’s receiving $15K/month from Britney, but that was decided under the original custody agreement, which gave them 50/50 custody. Now K-Fed has the kids 6 nights a week and nearly every day. Plus he’s court-ordered to have security for them, but the court’s not paying for that security.

So he’s going back to court to ask for more mula.

Brit-Brit has hired a private investigator to track K-Fed’s behavior with their two kids, since K-Fed already has about 100 paparazzi as his P.I.s.

One source says, during their marriage, Spears witnessed K-Fed smoking dope and drinking beer around the kids. Brit’s camp hopes they can get the goods and turn the tables in the custody battle.

Kevin gets the kids on Thanksgiving.

Brit gets them the day before.

Probably as it should be.

Look, Britney, I know you know you’re hot, girl. I know you get all sorts of dudes comin’ up in here tryin’ to get your number, baby. And I know you like fuckin’ with ‘em, givin’ ‘em all sorts of digits that ain’t real. But I’m different from those dudes. You gotta believe me, girl. I’m not like all those losers. And I’ll tell you why, baby.

I’m a Superior Court of the State of California.

The court today strictly reminded Britney that she had to give them a single number on which she could be called in for random drug testing, after K-Fed dragged her ass to court again for failing to respond to the drug testing calls.

“There needs to be one number that the testing facility calls that she responds to,” ruled the Commissioner. He did not make any changes to the existing custody agreement.

“I blame myself. What mother wouldn’t? I wish I’d been there more while she was touring. But I couldn’t be. I had the other kids to look after … I didn’t raise my children to have Hollywood careers. This all just exploded in my face, and big dreams became big headaches … Here are two parents who care about their kids. They’re good people. With my daughter’s, Kevin’s and the boys’ interest at heart, I’m trying my best to bring them together, to bridge the gap. I think things are getting good.”

Kevin recently decided to take Britney to court again, seeking to limit her already measly visitation rights.

Yes, Lynne. Things are just starting to get good.

For me, at least.

Ack.

Kevin is dragging Brit’s ass back into the courtroom, arguing that she violated the court’s drug testing order by failing to respond in a timely manner when she is called for random drug testing.

He wants her to have even less visitation rights with their two sons.

Hell hath no fury like a back-up dancer scorned.
