Britney Spears News

Los Angeles (E! Online) – The Circus is going international—and so are Britney Spears' sons!

Kevin Federline's longtime attorney tells E! News that K-Fed and his ex-wife will be extending their current custody arrangement when Spears' blockbuster tour crosses the Atlantic.

Meaning, Federline will also be making the trek to Europe so that Spears can continue to be close to sons Sean and Jayden—and the boys' dad will be around to take care of them when mommy is onstage.

"They worked out an arrangement to facilitate her being able to go on tour without having to sacrifice her abiltity to see the kids," attorney Mark Vincent Kaplan says. "She'll go on tour, she'll go to the venues, but Kevin will be there with the kids. There won't be any change in the custody schedule in Europe or anywhere she is on tour."

The once-estranged exes first hammered out a modified joint custody deal when Spears embarked on her Circus tour in March in New Orleans.

"Kevin is happy with how the kids are doing, and he's happy that he's been able to work out an arrangement where Britney is pursuing her professional goals, and Kevin is rooting for her all the way," Kaplan says.

My, how far they've come. "The kids are great, they're really happy," Kaplan adds. "They're very well-adjusted kids, as well-adjusted as you can expect. They will always push the envelope, but I think that they have the absolute privilege of having two parents who absolutely love them. Everyone has worked for making sure that they're not a product of all of the attention and commotion."

As for Federline's current squeeze, volleyball player Victoria Prince, Kaplan wouldn't confirm whether she'd be a member of the overseas entourage, but he says that she has spent time with Sean and Jayden and "they have a good relationship."

The Circus Starring Britney Spears is off to London in time to kick off an eight-show engagement at O2 Arena, after which it's off to Dublin, Paris, Stockholm, etc., before the tour wraps up July 26 in Berlin.

Meanwhile, as the money rolls in from Brit's comeback extravaganza, her estate has noticed that an awful lot of dough has been rolling out, as well.

Hence the motion filed by Spears' legal camp Friday requesting that Sam Lutfi be ordered to reimburse Spears for $123,142 in legal fees to cover what it cost to fight for the three-year restraining order that was, after a drawn-out struggle, put in place against Lutfi last month.

They would also like another $129,922 from fellow restraining order target Jon Eardley and $72,292 from Britney's ex, Adnan Ghalib, all of whom have been ordered to stay away from the popster until April 2012.
