Sean "Diddy" Combs and his off again/on again girlfriend Cassie were spotted leaving Le Meurice hotel in France over the weekend, and later we spotted the lovebirds shopping at Givenchy, Chopard and Rolex. Cassie is busy promoting her new single, "King of Hearts," but it looks like she also has plenty of time to play around in Paris. And on Diddy's dime? Lucky her!

It's being reported that Cameron Diaz has reunited with rumored flame Sean "Diddy" Combs, and a source tells Us Weekly that the two "had their hands all over each other" when they dined at Catch in New York City on October 24. When the duo lunched at Scarpetta in Beverly Hills last Friday, they were "making out, acting romantic," says another source. The mag claims Diddy has been "her off-and-on hookup since 2008," and a source added, "When she's single, she'll booty call him."

Of course, Diddy is still dating R&B hottie Cassie, and Cameron's rep tells X17online, "Cameron and Sean are longtime friends and fans of one another's work. They have been seen together recently because they are developing a film project. They are not romantically involved." And People mag reports that it wasn't exactly a romantic lunch date -- though the two were alone for the first part of the meal, they were joined by a man who appeared to be a business associate.

Hmm, what do you think is going on? Is Cameron really getting down and dirty with Diddy?!

Rap superstar Diddy and sexy R&B diva Christina Milian know how to have sexy fun in the summertime!

Diddy, 41, hosted a wet and wild party at the Palms Pool & Bungalows at the Palms Casino Resort in Las Vegas. We're told the rap mogul grabbed the mic and got the crowd going nuts with a performance of “Mo Money Mo Problems."

Milian, 29, left baby Violet at home for some quality adult time. Looking good, Christina!

Sean 'P. Diddy' Combs is living the life!

We caught up with the rapper while he was lounging on a yacht enjoying a cigar in Saint Tropez, France, before heading to the VIP Room, where he invited all of the locals to join him, Tweeting: "ST TROPEZ!!! VIP Night Club!! Meet me there NOW!! LETS GOOO!!!"

Earlier in the day, Combs donned a vibrant red shirt as he headed to the exclusive Pool Beach at Club 55 on gorgeous Pampelonne beach, where he spent the day partying with countless hotties in the club's VIP area.

It's good to be the Puff!

Find out what Combs' choice drink, the "DiddyUp", is made of, after the jump ...

Everybody likes a nice glass of white wine on a hot day, but not while you're walking down the streets of LA and getting into your chauffeur-driven car! Sure, we'd all like like high rollin' like that, but we don't dare do it!

P. Diddy just settled his decade-old lawsuit filed by the victims of a gun shooting in a nightclub way back when when Diddy was Daddy and J Lo was on his arm.

Remember that Christmas 1999 incident in which Diddy's protege Jamal "Shyne" Barrows pulled out a gun and shot a few fellow club-goers in a New York club after a fight broke out and the gun ended up in Diddy's car? Well the king of rap ponied up a reported $1.8 million for victime Natania Reuben, who was shot in the face that night, and a few hundred thousand went to two other victims as well.

So this is how Diddy celebrates? Sipping wine on the streets of LA just a day after the verdict? Let's face it, $1.8 million is a drop in the bucket for this music mogul -- and only a portion of that money actually came from P's pocket (the club's insurance company kicked in a significant portion).

But this raises a more important question ... should Diddy be drinking alcohol in a car, even if he's not driving? Something tells me the LAPD would say, "NO!"

Jennifer Lopez is only a few months into her American Idol role, and she's already making an impact on one of the music industry's biggest performers ... who also happens to be her ex.

P. Diddy says JLo has brought him to tears because of her compassionate judging style on AI. Diddy tells Access Hollywood:

"The way [Jennifer] handled coming after Simon, and even myself from Making the Band and the way we were hard coaches - she's been like, a compassionate person. She's made me cry like, twice, and she's looked good doing it. And she's made sense so, you know, I'm proud of her. She's a nice person so, you know, when you're super nice, your emotions get the best of you."

JLo and Diddy dated back in 1999 but ended their relationship in 2001 after they were both arrested on charges involving a shooting at a New York nightclub.

As for his thoughts on JLo revamping the judging panel, Diddy adds, "It's good though - it's good to see that change in the competitive shows. I think she's very refreshing."

Diddy will be joining Lopez on American Idol. Find out when ... after the jump.

Sean "P. Diddy" Combs has passed on his musical talents to adorable 4-year-old daughter Chance.

Listen to the little cutie give it her all while performing Feliz Navidad on a pink piano ... while daddy Combs rolls the camera. Can't help but notice her sassy black beret and stylish white top. So darn cute!

Watch out Willow Smith! There's a new pint-sized performer in town.

P. Diddy may look tough, but he's got a soft spot for supermodels ... gee, surprised?!

Yesterday in St. Barth, the rap mogul sported a t-shirt emblazoned with a big ass photo of Naomi Campbell on the front and we're loving it!

Only Diddy could pull off a shirt like that and then ride away into the sunset on this ...

Dayum!
