Katie Holmes and Christina Aguilera have both signed on to star together in the drama, Humboldt Park. Shooting for the film will begin in February of 2008, weeks after Christina is due to give birth to her first child.

A source says, “(Holmes) is trying to prove she can do more than fluffy popcorn movies“, and starring alongside Aguilera “shows she’s willing to take risks“.

Christina Aguilera got hand from hubby Jordan Bratman as they headed out to celebrate her 27th birthday Tuesday at Houston’s in Beverly Hills. Can you believe she is 27?! Remeber when her & Britney just hit the music scene … ?  Ahh, the good ole days.

Reportedly, Mrs. Bratman is carrying a boy- what’s that myth about if the belly carries high it’s a boy, & if it’s low it’s a girl … ?

The popstar reveals in the latest issue of Marie Claire on what a surprise her pregnancy was:

“We were planning on starting to try after the tour. And so, I had gone off the Pill to prepare my body, because I didn’t know how much time it would take. You’ve heard it takes some time — except with Power Egg and Super Sperm here… I’m like, Oh, my God, can you believe it just happened?”

To read more of the interview, grab the issue when it hits newsstands on December 11th.  Does anyone else think the cover might have been airbrushed?  Don’t get me wrong, she looks fantastic, but take a look at the picture below from November 25th- the face & belly sizes just don’t match …

It was a happy second wedding anniversary for Christina Aguilera & her music producer hubby Jordan Bratman. The couple got dressed up for a stylish dinner outing at Amalfi, taking advantage of the last year in which they don’t have to arrange for a babysitter.

Christina and Jordan are expecting their first child together in early 2008, & have been busy going through the motions leading up to their baby’s arrival. Just this past weekend, Christina Milian, who attended Aguilera’s baby shower, told press: “Her son is going to be pretty lucky because his mom … she’s just awesome. She is going to be a cool mom.”
