Well, we didn't see this coming.

Celebrity chef Nigella Lawson's husband Charles Saatchi is filing for divorce. The art mogul told U.K.'s Daily Mail on Sunday that he's disappointed his wife didn't publicly defend him following their fight at a London restaurant in early June. Photos surfaced of Charles grabbing Nigella's throat during the lunch date where she appeared to be crying and visibly upset. Charles was given a police "caution" after admitting assault.

This is heartbreaking for both of us as our love was very deep, but in the last year we have become estranged and drifted apart. I feel that I have clearly been a disappointment to Nigella during the last year or so, and I am disappointed that she was advised to make no public comment to explain that I abhor violence of any kind against women, and have never abused her physically in any way.

He also suggested in the statement that Lawson herself has grasped his neck in the past.

The row photographed at Scott's restaurant could equally have been Nigella grasping my neck to hold my attention -- as indeed she has done in the past.

Charles defended his actions after the incident made headlines, describing it as a "playful tiff" during an intense conversation about their children. Nigella has two kids with her late first husband, journalist John Diamond, and Charles has a daughter from a previous marriage. The couple wed in 2003.

John Mayer kicked off his Born and Raised World Tour at the Marcus Amphitheatre in Milwaukee, Wisconsin on Saturday night, an the singer gave lady love Katy Perry a sweet shout out while performing "A Face to Call Home," telling the crowd that Katy is "my face to call home." Of course, Katy was watching from onstage!

In a recent interview with Rolling Stone, Mayer credits Perry for sticking by his side when he suffered vocal chord problems that left him unable to sing or speak for about 20 months. "She was so patient," he said, adding that she took the time "to continue to get know me and love me" despite the vocal impairment.

The lovebirds first started dating in the summer of 2012, they broke up that August and then they got back together again in September, only to split again in March. The couple's romance heated back up later this spring when John attended a Memorial Day bash at Katy's new Hollywood Hills home.

Gisele Bundchen posted this adorable photo of her daughter Vivian on Instagram over the weekend, and the supermodel wrote, "The best love in the world!" Awww!

Last week Gisele and hubby Tom Brady took sons Jack and Benjamin to Disney's California Adventure Park, but 7-month-old Vivian was left out of that trip. So what's life like with two boys and a little lady?

Tom recently told ESPN, "I grew up in a house with three sisters. I think it's great for my boys to have a girl in the house, just to understand at least a little bit about what makes a woman tick -- not that I can certainly figure that out, because I can't."

Seeing as he's married to a former Victoria's Secret model, we'd say he has an idea!

Jennifer Aniston and Justin Theroux reunited in Los Angeles amid rumors of a breakup and X17online has the EXCLUSIVE PHOTOS!

For those who thought the wedding was off, these pix confirm it's definitely STILL ON!

We snapped the pair shopping together at Maxfield in Beverly Hills, as Aniston left with a garment bag and a tote full of goodies.

As the couple finishes renovations on their $21 million Bel Air home -- which they've already moved into -- Jen's finished shooting We're the Millers and has an untitled Elmore Leondard project in post-production, in addition to two films in pre-production including Miss You Already set to start shooting this summer.

Meanwhile, Justin's been in New York for a few weeks and while some reports claimed he moved there, those in the know (aka X17), realize Justin's ALWAYS had a place in the city and that he preferred to stay there while Jen was on location since their new LA manse was still under construction. Reports said the couple was breaking up due to Jen's unwillingness to move to NYC but the pair was simply waiting for all the drilling and hammering to finish before reuniting in their 90210 palace!

Kourtney Kardashian and baby daddy Scott Disick enjoyed some time without the kids, partying in Vegas this weekend ahead of daughter Penelope's birthday tomorrow.

The two-time mom wore a bright orange dress with neon yellow bandeau bikini underneath as she stepped off the plane in Burbank, Calif. Kourt wore some gorgeous, multi-colored heels to match.

The reality show star rushed back to LA to finish preparations for Penelope's first birthday on Monday. Happy birthday, P!

Paris Hilton was treating someone to cupcakes on the beach in Malibu Saturday. But the looks of her bangin' bod, it wasn't for her!

So we're guessing her boyfriend River was maxin' and relaxin' on the sand, waiting for his lovely lady to bring him a treat. And boy, did he get a treat ...

Meanwhile, as Paris shopped with River later in the day at the Malibu Country Mart, we asked her about her upcoming album with Cash Money Records ...

Halle Berry showed off her growing belly Saturday in a flowing black sundress while shopping with a friend. She even indulged her pregnancy cravings with some gourmet Mexican cuisine at Pink Taco. Guess Halle likes it spicy!

No word on the 46-year-old's due date, though baby daddy Olivier Martinez DID let it slip the couple's having a boy. And as Halle flashed her engagement ring, we also still don't know about the her wedding plans. We're guessing she'll wait until after the baby's born, since that date is fast approaching. Maybe a summer 2014 wedding for Halle and Olivier?

Taylor Swift posted an entire ALBUM of photos of her 4th of July celebration with her "touring family," on Friday.

The 23-year-old went Instagram-crazy with her backup dancers at her Rhode Island manse, posting pix of the kids playing ping pong, hopping around the green lawn, waving American flags and drinking out of red solo cups. Fun!
