Kanye West debuted several unreleased tracks from his upcoming Cruel Summer album at the PH-D Rooftop Lounge in NYC over the weekend, and the rapper has revealed that one of the new tunes is about ladylove Kim Kardashian!

Kanye tweeted, "I wrote the song Perfect B*tch about Kim," and according to NYDN, "[He raps] verses about his search for the perfect woman and how he has now found the 'perfect b*tch.'" An insider at the club added that the song also contained "a number of descriptions that reference Kardashian's famous curves."

And this isn't the first time Kanye has penned a few lyrics about his ladylove! Back in April, he rapped about Kim on his track "Theraflu," revealing that he fell for her when she was still with hubby Kris Humphries and declaring that he wanted "to put [her] in a white dress."

Pauly D (nee Paul DelVecchio) headed to Starbucks in NoHo yesterday, and the reality TV star flashed us his pearly whites on the way out.

Seeing as Forbes just named him seventh wealthiest DJ in the world last week, he's got plenty to smile about! Pauly D reportedly raked in $11 million last year, but he insists that he's pretty conservative when it comes to spending his dough -- except when it comes to watches.

And speaking of bling, what's with the necklace? It turns out the Rhode Island native is helping 50 Cent promote his SK Energy Shots, which launched in October 2011. Back in September of the same year, the rapper publicly committed to donating one billion meals to the World Food Program over five years, and so far he's already donated 3.5 million.

Gwen Stefani looks picture perfect in pink!

The 42-year-old No Doubt singer, channeling her inner Barbie doll for Harper's Bazaar, opened up about maintaining such a fabulous form.

Stefani tells the fashion mag: "There is no secret: You just have to eat healthy, work out, and torture yourself!"

Gwen ruffled outfit by Alexander McQueen is so adorable!

As for her trademark red lips, the mother of two says Gavin loves the look. She adds:

"I like to make my husband [Gavin Rossdale] like me more, and he likes it when I'm wearing makeup."

The sexy twosome hit the beach in West Palm Beach over the weekend for some PDA in the sand. Gotta love Gwen's red lips ... even on a casual beach day!

Kimmy K sure knows how to start her day off on the right foot - literally!

The reality star was up bright and early to catch a Pilates class with a girlfriend, and after sculpting her enviable bod she grabbed a soda - gasp! - and headed to a local nail salon for a quick mani/pedi.

The brunette bombshell put her best assets on display in tight black spandex, and she looked so amazing that we almost didn't realize she opted for a makeup free fresh faced look!

Kanye is one lucky dude!

Justin Bieber is currently busy preparing for his Believe Tour, and we snapped him on his way to a rehearsal in Hollywood yesterday. Nice watch BTW ... that probably cost a pretty penny!

It was just announced that the 18-year-old pop superstar is giving his fans the chance to dance with him onstage, as his tour director Jon M Chu has launched a website for fans around the world to upload videos of themselves. “When I started it was on YouTube… Why can’t it happen for you? #BELIEVE in YOURSELF,” Bieber wrote on Twitter.

In other other Biebs news, he's angered plenty of folks in the UK over recent comments about Prince William's hair. In an interview with Rollercoaster magazine, Justin said, "I mean, there are things to prevent that nowadays, like Propecia. I don't know why he doesn't just get those things, those products. You just take Propecia and your hair grows back. Have you not got it over here?"


Talk about a royal insult! Think he'll be issuing an apology about this?

He's one talented teen!

Jaden Smith debuted his music video for his latest single "Pumped Up Kicks (Like Me)" and we're loving his raps over the sampled Foster the People track! Will and Jada's son shows some serious swagger as he skateboards with friends and hangs out with beautiful girls.

We wonder if his pal Justin Bieber gave him some pointers on how to look cool?

The 14-year-old is making quite the name for himself in Hollywood! Not only is he planning to release a mix tape this autumn, he's also the highest paid child star in the industry! The vivacious high schooler netted a reported $3 million for his role in the Karate Kid remake.

The only thing that would make this music video better would be a guest appearance by his sister Willow!

Madonna was in ultra-fine form while hitting the red carpet for the opening of "HardCandy" Fitness Club in Moscow, Russia.

The 53-year-old entertainer, who was dressed in all black, may have raided her younger daughter Lourdes' closet for this event. But regardless, Madge still holds her own.

As for why she chose to open a club in Russia, Madonna said the following:

"Well I can say why I chose Moscow. Because I, first of all, I love the city, and I had a very good experience when I came here with my show. And second of all, I feel like people here really have a good work ethic, and are really into fitness and work long hours, and I thought this was a really good place to start a gym.”

By the way, we're lovin' those Chanel fingerless gloves!

Mother Monster loves her man!

Lady Gaga definitely isn't the type to shy away from attention... especially when it's coming from her super hot boyfriend Taylor Kinney! The pop singer shared a passionate embrace skinny dipping with the Vampire Diaries actor and posted the pic to her official website with the caption, "T and Me."

The couple, who met filming her "You and I" music video in 2011, have been spending a lot of quality time together while the Grammy winner is on a break from her 110-date Born This Way Ball worldwide tour. The sexy pair even enjoyed a meal with Gagaloo's parents in New York over the weekend!

Is a trip down the altar next for these lovebirds?! We can only imagine how over-the-top that wedding would be!
