Christina Aguilera posed for pictures at the World Hunger Relief's "Pass the Red Cup" challenge in Los Angeles on Tuesday, and the 33-year-old starlet showed off her baby bump in a white dress and denim jacket. Lookin' good, Xtina!

Aguilera has served as a global spokesperson for WHR since 2009, and yesterday she tweeted, "Join me and #PassTheRedCup by donating $5 to feed 20 children for @yumbrands @WldHungerRelief." WHR benefits the U.N. World Food Programme), and Xtina recently spoke out about why this cause was so important to her.

"It's heartbreaking to me that in our social media driven, increasingly-connected world, nearly 850 million people go to bed hungry each night," she wrote in an article published on the Huffington Post. "And this includes far too many children. It's a subject so close to my heart and has been for a long time, being a mom."

On spending time at a refugee camp in Rwanda she added, "They told me how they escaped violence in the Democratic Republic of Congo. Their courage and hope for a better life was incredible. On my trip, I served food to kids who walk miles to and from school each day to receive a hot meal. I also went to Haiti after the earthquake hit a few years ago and saw its devastating effects on many families. Kids there were so happy just to get rice and beans from WFP."

Not only did Miley Cyrus post a photo of herself in a bikini smoking what looks like a blunt, but yesterday she also Instagrammed two pictures of her latest tattoos!

Miley had one more day in New York City before heading to North Carolina for her next Bangerz concert, so naturally she spent her last night in town at a pool party and showing off her new ink! The first tat pays homage to her pal Wayne Coyne of the Flaming Lips, as "Love Yer Brain" is a tune from the band's 1987 album Oh My Gawd!!

The crescent moon inside her left arm is apparently a matching piece that celebrity tattoo artist Bang Bang also inked on himself. "BFF tats with @bangbangnyc," she wrote. Bang Bang has inked everyone from Cara Delevingne to Rihanna, and he's done a bunch of Miley's body art as well. At this point we've lost track of how many Miley has!

Sending a message?

Kendra Wilkinson took a trip to the nail salon in L.A. yesterday, and the reality star made no attempt to hide that she wasn't wearing her wedding ring! Maybe it's because the mother-of-two has finally come to terms with the fact her marriage to husband Hank Baskett is dunzo?

Apparently the former Playboy playmate is getting business in order for a split, after news broke earlier this month that her football player hubby cheated with transsexual model Ava London. "Kendra's definitely looking into divorce. She's met with lawyers and is weighing her options," a source dished to Life & Style.

So why did the blonde bombshell decide to finally pull the plug? "Her family is saying she should leave Hank — that he’s a cheater, through and through. She’s the type of girl that believes once a cheater, always a cheater,” the source added.

She should have just stayed with Hugh Hefner!

Getting some advice on consciously uncoupling, perhaps?

The other day Beyonce Knowles posted some sexy and solo photos of herself on Instagram, and it turns out they were snapped at Gwyneth Paltrow's multi-million dollar Brentwood home! We knew the ladies were pals, but we didn't realize they were this close...

Bey was in Los Angeles over the weekend for her On the Run tour with Jay Z, and with rumors running rampant that the famous couple are about to split, it seems like the Grammy winner is already preparing for her life as a single lady. For what it's worth, there are also reports that Jay and Bey are staying in different hotels and arriving to their shows separately, and last month it was reportedly the Beyonce was checking out posh apartments in N.Y.C. by herself.

Though Beyonce has posted several Instagram and Tumblr photos of herself and Jay Z looking all lovey dovey, a source tells Page Six, "This may not make it to [their concert in] San Francisco. I'm definitely not sure that they'll make it to Paris. They’ve had discussions lately about the inevitable sit-down interview when they finally do split, and Jay’s been adamant that he doesn’t want Beyoncé sitting down with Barbara Walters or Oprah Winfrey pretending to be the victim."

Megan Fox is still making the promotional rounds for Teenage Mutant Ninja Turtles, and her latest stop took her to the Apple store in New York City on Tuesday, where she greeted fans and answered dozens of questions during a Q&A.

The 28-year-old starlet looked amazing in a tight black and green dress with green Valentino pumps, and she recently revealed that she cut carbs and sugar out of her diet to drop the weight she gained when she was pregnant with her second son Bodhi. She told E! News last week, "It's kind of awful but it's what I'm doing."

So what about some of the stunts we see onscreen? "We did initially start out doing some kickboxing training," Fox told reporters at a junket for the film in West Hollywood on Friday. "They would teach me on site because we had an incredible stunt team … They were the best of the best. I was pregnant also so I couldn't do all of the stunts well while I was filming. What I couldn't do we had an amazing stunt girl to do the serious stuff for me. But I did what I could -- and that was a lot."

We bet! TMNT hits the big screen this Friday...

Well, former gigolo boyfriend, we should say. Now that he's cruising around Hollywood in Lea Michele's Range Rover and vacationing with the actress on Italy's Amalfi Coast, Matthew Paetz's days of selling his body to the highest bidder are long over! That is, until the Glee starlet dumps him…

Lea and her boyfriend went for a hike on Tuesday afternoon, and is it just us or did she seem a little bit uncomfortable when he tried to plant a smooch on her in front of the cameras? We're not sure if it was because she was sweaty or because she wasn't feeling like putting the P in PDA, but it is interesting that Mr. Male Escort seems to be the one who wants to play it up in front of photographers. After that the duo grabbed smoothies at EarthBar, and they later returned to her Los Angeles home.

The two started dating shortly after they met in April, but given how much time he's spent with her friends over the last few months, it seems like they approve...

Well, this outfit isn't going to win back Justin Bieber -- it's like Beetlejuice meets the Beatles!

On Tuesday afternoon Selena Gomez went to an office building in Calabasas, and the 22-year-old singer/actress wore a striped, sleeveless mock turtleneck with a pair of high-waisted black pants and boots. And those shades? Hmm ... let's just say we prefer them on Mary-Kate and Ashley!

Selena recently returned from St. Tropez, where she was spotted getting all kinds of cozy with hunky yacht businessman Tommy Chiabra, and around the time she returned, her bad boy ex-boyfriend jetted off to Ibiza. But now that they're both back in town, we're just counting down the days until a Jelena reunion...

She definitely has a glow about her!

Possibly pregnant Jennifer Garner was all smiles as she chatted on the phone on Tuesday afternoon. Looks like Band-Aid baby No. 4 is on the way!

The mom of three showed off a clear baby bump while doing a little retail therapy near her home in Brentwood, Calif. Last week pregnancy rumors flew when Ben Affleck's bride was spotted with an unmistakable growing belly. And now it seems impossible to deny what our eyes are telling us!

Given the way the fabric clings to her stomach -- she's definitely not trying to hide her curves. We expect a pregnancy announcement any day now!

While Jen and Ben have stayed mum on the baby issue, Star confirmed that the Alias star has a bun in the oven.

Despite recent reports of some major marital woes, including gambling and cheating allegations, it seems as though the twosome are committed to making it work.
