Christina Aguilera's son Max celebrated his 4th birthday on Thursday -- and did it with a trip with mom to a California theme park!
The two were spotted yesterday at Legoland with Christina's boyfriend Matt Rutler. Max's dad, Aguilera's ex husband Jordan Bratman, was nowhere to be seen.
The gang all hopped onto some Lego speedboats, where Max got behind the wheel!
Christina recently opened up to Marie Claire about being a single mom, telling the mag "It's a struggle. But I can't single out my ex-husband [as the problem] because he's a devoted father and great with my son.”
She adds, “We always make sure that we put Max first. I have help from family and good people around me in support of my career. I couldn't do what I do without a strong team behind me."
