Christina Aguilera and her son Max hit the high seas of Legoland Thursday to celebrate his birthday.
"The Voice" star's favorite little man turned four on January 12th and what better way to party, than with some rides. Max's dad, Aguilera's ex-husband Jordan Bratman, joined Aguilera, her boyfriend Matthew Rutler and Max for some theme park fun.
It looks like Aguilera and Bratman are following in the footsteps of some other stars, like Courteney Cox and David Arquette, who've managed to have a happy and healthy post-divorce relationship.
