Christina Aguilera has a lot to celebrate ... the opening of Burlesque, her son and a 30th birthday around the corner!

While visiting The Ellen DeGeneres Show, the blonde singer was surprised with a life-size birthday cake and a shirtless cutey inside.

As for how she's dealing with her divorce, the starlet tells Ellen:

    "... my focus first and foremost is my son Max. More power to single moms and those out there doing it. I was raised by a single mom. But you know what, at the end of the day....He's the love of my life. I adore him and he's such a character and he's so happy and at the end of the day, that's what's most important."


Xtina doesn't turn the big 3 - 0 until December 18th, but who says you can't celebrate early!
