Christina Aguilera: Birthday Girl

Turning 28 years old never looked so good, and last night Christina Aguilera had some help celebrating a "Clockwork Orange" themed birthday from a few fellow Hollywood A-listers.

The “Ain’t No Other Man” songstress was joined by the likes of Paris Hilton, Nicole Richie, Joel and Benji Madden, and her husband Jordan Bratman as she converged on Osteria Mozza restaurant for a delicious dinner.

And now that she’s loving motherhood (she gave birth to son Max back in January), Christina is already thinking about and looking forward to another baby.

She recently told press, “This little one is a constant reminder of your love for one another. It’s also a work in progress because you’re constantly growing as people. It can be very challenging. It can be incredible and exciting. I got lucky. I have a great husband – he’s really supportive and I look forward to the next one."
