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.”
