Casper Smart is talking – and what he says is pretty interesting!

On June 8th, The Sun published a story accusing Jennifer Lopez’s boy toy of cheating on Jenny from the Block with transgender model Xristina Marie. During the controversy, Smart has remained mum about the Xristina Marie and another transgender model Sofie Vissa, who alleged she had a sexting relationship with the choreographer. But now Smart is saying that the claims are false.

“There is no truth to any meeting or physical encounter. I am weighing my options on the appropriate action to take against Xristina Marie and/or The Sun,” Smart said to Us Weekly.

He may have denied the sexual relationship – but he certainly isn’t denying the sexting!

We don’t know if there is truth to these accusations or not – but we know that JLo isn’t standing for them. On Friday, Us Weekly reported that the twosome had broken up, and added they've been split for some time now.

We think that Lopez is just trying to save face in light of the controversy -- but that's okay ... JLo can do no wrong in our eyes!

Despite the split, it looks like the Lopez isn't being entirely bitter. The 44-year-old isn't gifting her ex cash, ala Simon Cowell, but apparently her younger man can keep the motorcycles, jeep and Dodge Ram truck that the Wedding Planner star gifted him during their relationship, reports TMZ.

On Sunday, our photogs caught Smart leaving Lopez's Los Angeles house on the Kawasaki Ninja she gave him. Life doesn't seem too bad for JLo's ex!

Rihanna had a most unlikely dinner date last night ... with Gwyneth Paltrow's estranged hubby, Chris Martin!

The consciously-uncoupled Coldplay frontman and the sexy pop star arrived, separately, around 9pm and stayed for 2 hours! And catch this ... X17 can report exclusively, that Gwyneth had just headed to LAX for a flight to London before Chris jumped in his Jeep, headed for dinner with Rihanna at her favorite spot, Giorgio Baldi in Santa Monica.

Our photographer tells us the two were quite cozy during dinner: "They were leaning in to each other, laughing and being flirty. Rihanna kept pushing her hair out of her face and Chris appeared to be almost whispering in her ear."

The pair had a corner table to the Italian hotspot -- Rihanna's a regular at the restaurant. She toned down her usual over-the-top fashion and opted for a black sweater with ruffled sleeves and black pants with heels. Chris wore a tee-shirt and jeans.

Our shooter commented, "They looked cute together - maybe they're working on a new project; maybe they're trying to make certain people [Chris Martin and Gwyneth Paltrow] jealous or maybe they're actually dating. I was surprised to see them together!"

Chris and Rihanna have collaborated before on the track "Princess of China," in 2012, for Coldplay's fifth studio album Mylo Xyloto. They performed the single that year at the Grammy's. Click through to see that music video -- and check out our video from last night ...

Jennifer Lopez certainly isn't down in the dumps over her recent break up from choreographer Casper Smart! Over the weekend the 44-year-old singer/actress attended an event for her new album, and she Instagrammed the pic above and wrote, "The countdown is on!!! 10 days until #JLoAKA album release."

"Jennifer was in a great mood and really happy with the reception to the new music! People loved it," a source at the event told Us Weekly. "She was really happy. She has been so focused on launching this album and feeling really great."

After several websites claimed that Smart was fooling around with transsexual models earlier this month, a source told the mag on Friday that Lopez and Smart had split after two and a half years together. The source denies that Casper's alleged infidelity was to blame, adding, "The scandal had nothing to do with it. He insists none of that is true and she believes him."

"It has actually been an amicable process that started a few months ago," an insider tells Us. "It wasn't an easy decision, but they decided to stay friends ... Their relationship couldn't work with the distance. He started trying to establish his own life and career, and she is so focused on hers, and they just couldn't be all about each other anymore."

Later J. Lo posted the shot below and wrote, "Hope everyone is having a beautiful weekend!! #NYC #ilovesunnydays #imatiemyhairuptop." Looks like she's doing just fine:

Kourtney Kardashian and some gal pals lunched at Harlow in the Hamptons on Saturday, and the reality star may have kept her tiny baby bump covered with a loose top, but she couldn't hide her smile!

Last week the news broke that Kourt and partner Scott Disick were expecting their third child together, and while it hasn't been officially confirmed by a Kardashian family rep, no one's denied it! Between Kourt's pregnancy, Kim's recent wedding and all the drama with Rob, it looks like there will be plenty of great material for the next season of Keeping Up With The Kardashians...

Leave it to Gwen Stefani to look this gorgeous while grocery shopping!

On Saturday the cheerful No Doubt singer stopped by Whole Foods, and not only did she look amazing, but she carried her own bags to the car. Don't ever accuse her of being a diva!

The 44-year-old superstar always looks amazing, but the fact that she gave birth just three months ago never ceases to amaze us...

Andrew Garfield and Emma Stone lunched at Rose Cafe in Venice on Saturday, but they were so sneaky on the way out we almost didn't even catch them!

After Emma got in Andrew's car, the Spider-Man hottie had a light-hearted exchange with one of our photographers...

Despite the fact that they went for dramatically different looks, Ashlee and Jessica Simpson both looked gorgeous when X17 photographers snapped the ladies at a pal's baby shower in Hollywood on Saturday.

Jess showed off her slimmed-down bod in a short purple shift while Ashlee wore an all black pant suit and heels, and it looks like her elaborate hairdo took quite a bit of time to put together, but we totally dig it!

Jessica posted the pic below and tweeted, "Celebrating the most beautiful mommy to be @laurenz422 I absolutely love you with my whole heart!!"

Sandra Bullock was snapped at Craig's with pal Hugh Grant after the Guys' Choice Awards on Saturday night, and the 49-year-old actress looked stunning in a colorful Roland Mouret dress. We still can't believe she's 49, but this might explain why she was honored with the Decade of Hotness Award earlier in the evening!

Hugh, along with Sandy's former co-stars Matthew McConaughey and Keanu Reeves presented her with the prize at Sony Pictures Studios. But speaking of leading men, where was rumored beau Chris Evans?

Evans, 32, has reportedly had a crush on Sandra since he was a kid, and a source tells E! Online, “They are not in a relationship, but they are definitely hanging out and are in the early getting-to-know-each-other phase. They haven’t put a title on it, but they really like each other.”
