Jennifer Lopez posed for photos outside of her NYC hotel on Wednesday afternoon, and the 43-year-old singer/actress looked a-m-a-z-i-n-g in a form fitting nude jumpsuit. Sometimes we can't believe that she's in her 40s ... or that she gave birth to twins 4 years ago!

After stepping out for a lunch date with beau Casper Smart earlier in the day, J. Lo taped an appearance on Katie Couric's new show, Katie, which will air on Friday. She chatted with the TV host about leaving American Idol and motherhood, and we're also kinda hoping she'll dish some dirt on her romance with Casper, who is almost half her age. You know Katie's gonna ask about it!

Gwen Stefani and hubby Gavin Rossdale are such a gorgeous couple!

The twosome, who just celebrated their 10th wedding anniversary, seem to have it all ... killer looks, rockin' style and two adorable boys, Kingston and Zuma.

The No Doubt songstress ditched her trademark red lips for the afternoon date while effortlessly mixing a simple sleeveless tee with khakis and sexy heels. Such a fashionista!

We love how after a decade as husband and wife, these two rockers still walk hand in hand. Aww!

Jennifer Garner was snapped leaving the Viacom office in Santa Monica on Wednesday, and we'd love to know what this meeting was about!

The 40-year-old actress wore a rather conservative outfit, and while we're not that impressed with her pilgrim-inspired pumps, she still looked pretty good! I guess we won't be seeing her in skintight clothes or colorful wigs anytime soon ... Ahh, remember the Alias days?

Earlier in the day we spotted Jen sharing a smooch with hubby Ben Affleck outside of Brentwood Country Mart, and couple just returned home from the Toronto International Film Festival a few days ago, so it looks like they're having quite a busy work week.

Kate Hudson is looking oh-so-glam in the October issue of Harper's Bazaar.

The actress, who is a mom to 8-year-old son Ryder and 15-month-old son Bing, is engaged to rocker Matt Bellamy. As for whether they'll tie the knot, Hudson tells the mag:

"We'll do it eventually, but I want it to be right. I don't want to just do it, you know what I mean?"

Hudson was previously married to rocker Chris Robinson, and she's been dating Bellamy since Spring 2010. As for Bellamy's relationship with the boys, Kate adds, "He was immediately very protective and, you know, watchful."

Russell Brand was snapped en route to yoga on Wednesday, and yet again the 37-year-old British comedian went completely barefoot. While we would ask what rumored ladylove Geri Halliwell thinks about his dirty feet, it seems like the duo have already parted ways!

Russell has reportedly been bragging about getting it on with a new conquest, and a source tells Now Magazine that Geri "is quite upset."

“She feels she's made a complete fool of herself again and she's still making the same old mistakes," the source added. "She was so excited when Russell was all over her and quickly got carried away trying to make all these future plans with him ... He just saw it as a bit of fun, a fling, and thought it was hilarious that she made it out to be something more serious. It's totally humiliating for Geri. He's made her look stupid.” Ouch!

Jennifer Lopez is taking in the sights and sounds of New York with her young boyfriend Casper Smart.

The hot couple returned to the Tribeca Hotel in the Big Apple after taping a segment for The Katie Couric Show.

While in NYC, JLo, 43, and Casper, 25, also hit up the Broadway play Evita starring Ricky Martin.

Great to see these two lovebirds still going strong!

Christina Aguilera's latest single "Your Body" will be released Friday, but we're getting an early glimpse of the sexy cover art.

Xtina, 31, Tweeted the above photo and the following: “Album comes out in November. #YourBody out Friday! Love you all! XoXtina.”

With promotion for her new album and her job on NBC's The Voice, sounds like the mother of one is going to be mighty busy!

John Travolta and Kelly Preston struck a pose outside of the George V hotel in Paris with son Benjamin today, and the happy couple were later joined by their 12-year-old daughter Ella Bleu at Pizza Pino restaurant.

John and Kelly are in Paris to celebrate their 21st wedding anniversary, and they even flew out a small group of friends for the occasion. On September 5, 1991 the lovebirds had a ceremony at the Hotel de Crillon in Paris, but since their first nuptials were officiated by a French Scientology minister, they had to have a second "official" ceremony on September 12 in Daytona Beach, Florida.

No word on whether any masseuses were invited...
