In the new annual Hot Bodies issue of Us Weekly, new mom Christina Aguilera — who welcomed son Max in January — shares the diet and workout secrets behind her 40 pounds weight loss .

In the interview, she also finally addresses the famous growth in her chest that came from breastfeeding.

“It’s kind of hilarious! I’ve never fit into an E-cup before,” she tells Us. “I look at my husband and go, ‘Guess what size this bra is?’ And when I tell him, he’s just amazed. We keep the tags that prove it, to look back for memory’s sake!”

For more on the best diets this summer and interviews with this year’s Hottest Bodies, including Kelly Ripa and Fergie, pick up the new issue of Us Weekly, on newsstands now.

It seems like Nicole Kidman is rekindling her sex appeal while embracing her motherhood.  I feel like she’s been pregnant for-ev-er… does anyone even remember this side of Nicole!?

But soon she will amp up the sex appeal, because she will be joining the ranks with Demi Moore, Britney Spears and Christina Aguilera- and pose nude.

She is so excited about her growing belly that she’s hired renowned photographer Patrick Demarchelier to take photos of her in the nude.

Don’t expect the pics to come out soon, though.  A source told the New York Daily News, “Nicole wants to wait until she looks really pregnant.”

Nicole’s bump seems like it grew overnight (look how tiny she is in the picture below!), she was absolutely glowing on the orange carpet at the Country Awards in Vegas this past weekend.

She is pregnant with her first biological child with husband, Keith Urban.

The baby is due in July, so expect the pics definitely before then!

Damn! Christina Aguilera is definitely on the ball lately with regards to showing off her gi-normous breasts! It was only yesterday when we saw her unleashing the beasts and now look at these bra-busting pictures! It’s quite obvious Christina is proud of what motherhood has blessed her with.

You can pretty much count on Christina to show us more in the near future. Well, at least you hope so! I know if I had them bad boys I’d be releasing the twins as much as possible!

Blue veins aside, I would totally drizzle some sticky maple syrup all over those tits and just shove them in my mouth and suck on them for hours and hours on end.

With one breast in each hand, my mouth slowly swirling from left nipple to right nipple and back and forth and back and forth and in and out and in and… um, sorry. I’ll take my fingers out from inside me now.

Marisa Miller becomes the first to debut in the number one position on Maxim Magazine’s Hot 100 list, which was just released this week. And oddly enough, Marisa had previously never been included in the Hot 100 list, but this was an exceptional year for the model. Not only did she grace the cover of Sports Illustrated’s Swimsuit edition, she was added to and took home the number one spot on Maxim’s Hot list.

Marisa was followed by Scarlett Johansson, Jessica Biel, Eva Longoria Parker, Sarah Michelle Gellar, Elisha Cuthbert, Eva Mendes, Christina Aguilera, Lindsay Lohan and Ashley Tisdale to round out the top 10.

Actress Megan Fox, who was FHM’s Sexiest Woman in the World in 2008, was only garnered the number 16 position. Other women who were listed are Rihanna, Beyonce, Britney Spears, Jessica Alba, Hilary Duff, Heidi Klum, Jessica Simpson, Charlize Theron, Gabrielle Union, Mariah Carey, Cameron Diaz and Mischa Barton.

And pulling off a trifecta for “The Hills” stars, Heidi Montag, Lauren Conrad and Audrina Patridge all made the Maxim Top 100 list, in addition to everyone’s favorite reality star and MySpace queen, Tila Tequila. However, congratulations are in order for Marisa Miller!

Wow, I must say Christina Aguilera is looking mighty sexy attending the Christian Dior 2009 Cruise Collection. Just look how Christina matches those pink shoes with her lipstick color, that’s just pure talent I tell ya! I think I’ve seen that shade of pink somewhere else though. Oh yeah, it resembles what Nicole Scherzinger was showing off the other day… her hot pink panties!
