Chaz Bono has his white tank top on once again, and that only means one thing ... he's ready for business on the dance floor!

Sonny and Cher's child Tweeted:

"It's Monday again and @LaceySchwimmer and will be doing our best to kick some quick step butt."

Last week on Dancing With The Stars, Chaz and pro partner Lacey Schwimmer gave us a memorable cha cha. Let's see if they can work their magic on this week's show.

We'll be watching!

Kim Kardashian hit two very contrasting milestones on Monday.

First, the reality starlet reached the benchmark of 10 million Twitter followers. That puts her at around the same social media level as President Obama, who has 10.2 million followers.

Kim Tweeted:

"OOOMMMGGG I just realized that I hit 10 MILLION FOLLOWERS! Words can't even begin to express the love I feel for all of u!!! ... I gotta do something special for u guys! Let me think of something fab to show my appreciation!!!!"

But her OMG's and exclamation points might be indicative of another title Kim received -- she was just voted Most Annoying Celebrity in a PARADE Magazine/Yahoo! poll. Kim won with 29 percent of the vote, beating out Charlie Sheen, Snooki and Donald Trump.

Kim's luck hasn't been so hot lately. The starlet just found out that Vivid Entertainment will not be selling her sex tape to a buyer who offered the company $20 million for it -- an offer that would have potentially taken it off the market.

Age is just a number!

J.Lo might be 42, but she looks 22! The singer/actress stunned in Las Vegas over the weekend, where she performed "Papi" at the iHeartRadio Music Festival.

Clad in a short, low-cut red dress, Lopez performed, then headed out to party. She hit Pure Nightclub with an an entourage of about a dozen people. At the club, one of her backup dancers gave her a shirtless lap dance in the VIP area, where she drank Dom Perignon Rose while her own music videos played on screens at the club.

Jen did graciously spend time shaking hands with fans at the club, but then headed back to the private area and didn't leave until 3:30 a.m.!

Lopez separated from hubby Marc Anthony in July -- she's single and loving it!

On Sunday night, Lady Gaga fulfilled her promise from last week; she met with President Obama.

Gaga paid the $35,800 required to attend an intimate Silicon Valley fundraiser for Obama held Sunday night at the home of Facebook's Chief Operating Officer, Sheryl Sandberg.

The pop star wore a black, sleeveless lace gown with a veil, high heels and a blonde boufant. Whether the two discussed Gaga's anti-bullying campaign, which she promised to meet with the President over, is still unclear. The President did not address Gaga in his opening remarks at the event.

Mother Monster vowed via Twitter last week to meet with the President after a 14-year-old fan committed suicide because of bullying. Gaga wants to make bullying a hate crime and enact stronger laws against it.

LeAnn Rimes has taken her sexiness abroad to London!

With her new album Lady and Gentlemen out tomorrow, the country singer wearing a stunning beige dress and sweater, has been busy promoting her latest effort. Love the brown suede heels!

While in the UK, Eddie Cibrian's wifey performed Sunday at "Songs of Praise" at the Alexander Palace. Joining her onstage ... superstar tenor Andrea Bocelli.

Now ... about that gold handcuff bracelet. Loves it!

As their romance continues to heat up, it's no wonder Miley Crus and boyfriend Liam Hemsworth decided to deck out their shared space with some romantic lighting, on Sunday.

The happy pair has been inseparable since rekindling their romance earlier this year, and it may have something to do with Hemsworth's low-key confidence.

“I think it’s someone that is always there to listen and I think that’s when people make mistakes because they always want to have the answers and I don’t like people trying to fix me. I just like them being able to listen,” Cyrus confessed to PhilStar.

Keeping it casual in a pair of comfy sweats, Hilary Duff stopped to feed her pregnancy cravings with some yummy Baja Fresh takeout in LA, on Sunday.

The former Disney star is gearing up to celebrate her 24th birthday on Sept. 28, and she kicked off the festivities this weekend with a 50's theme bday bash.

Duff shared a Twitpic with hubby Mike Cormie in vintage-style gear, with the caption, "50's themed birthday party!!! Rockin out to oldies!", and they look absolutely adorable!

Happy birthday Hil!

The stars came out for the big Hollywood premiere of Cirque du Soleil's "Iris" at the Kodak Theater on Sunday, and Vanessa Hudgens was sweet enough to bring her sis along to opening night.

The Beastly star looked hippie-chic in a full length maxi dress with feather motif, paired with a long white scarf and platform shoes, while little sis Stella opted for a much shorter dress and turquoise head scarf.

In other news, the former High School Musical star is gearing up to appear alongside Nicolas Cage and John Cusack in the upcoming film, The Frozen Ground.

The film, based on actual events, is set to hit theaters December 2012.
