Mel B's husband, Stephen Belafonte, is following her lead and still rocking his wedding ring, but it's not stopping him from chatting up a mystery woman ... who had shades of his estranged wife.

Stephen then hit the liquor store before heading to the Beverly Hills Hotel and Serafina in WeHo -- where he's an owner -- he was spotted chatting up a Mel B look-alike at dinner. She's even wearing the same shade of nail polish as MB.

The 'AGT' judge filed for divorce Monday after separating in December.

The force was not strong with the Lakers Tuesday night ... they got straight-up murdered by the Clippers -- but it all went down in front of a ton of huge stars including 'The Force Awakens' star Daisy Ridley!

The 24-year-old British actress (who played Rey in the flick) sat right on the court -- in a celeb-packed crowd that included Michael Phelps, Gucci Mane and Meghan Trainor.

Orlando Bloom's leaving us in suspense with a new cliff-hanger ... by jumping off a cliff.

Orlando's in St. Barts with Kristy Hinze and her billionaire husband James Clark -- been there since Friday, actually -- and he's getting over Katy Perry in exhilarating fashion.

Emily Ratajkowski left little to the imagination while lying out on the beach in Mexico.

Baking her buns, Emily looked like she might've opted for nude beach attire ... it's just a really tiny thong.

She's staying cool with cervezas, but that ass is in danger of a burn.

Justin Bieber took a load off ... and everyone was all smiles.

The Biebs hit up a bar in New Zealand and for some reason, decided to rip his shirt off before pounding a few back.

Bartender was all in.

Donald Trump Jr.'s son, Tristan, was taken to a hospital Sunday after breaking his leg in Aspen ... TMZ has learned.

We're told Secret Service accompanied the 5-year-old to the ER after he fractured his leg on the ski slopes.

Tristan was skiing with his family and Ivanka's family in Aspen over the weekend.

Justin Bieber was so totally unimpressed by something called "the world's most exciting jet boat ride" -- and it was written all over his face.

The Biebs had Monday off from his tour and hopped on a Shotover Jet in Queenstown, New Zealand. The high-speed boat hits 50 mph while careening and doing 360 turns. If that sounds like it'd be tons of fun ... it probably is, unless you're Justin.

Occupational hazard for a guy who drives exotic sports cars, we guess.

JB rented out the entire boat for himself and his 2 pals, so at least he was bored in private.

Barron Trump took a stroll around the White House with his parents on Friday ... the first time he's been seen there since Donald Trump took office.

The president's 10-year-old son walked across one of the lawns with Melania -- who was decked out in red -- before boarding Marine One to start a weekend trip to Mar-a-Lago.

Nick Viall and Vanessa Grimaldi are supposed to be engaged ... but you'd never guess it by the way they hang together when cameras aren't rolling.

Paps got America's newest favorite TV couple Thursday in Hollywood fresh off their 'Bachelor' finale earlier this week -- and they looked ... well, distant.

It's interesting ... they appeared cheerful as hell in front of a camera Tuesday in L.A.

But let's not forget their awkward onscreen reunion, which got people wondering if their post-'Bachelor' love was just a big sham.

Maybe they were having an off day ... you tell us.

Hillary Clinton and Huma Abedin teamed up again in NYC Thursday, as rumors swirl the former presidential candidate might make a run for mayor of the Big Apple.

Hillary and her loyal lieutenant hit up Bergdorf Goodman. Unclear if they were shopping or eating lunch.

The 2 are tight and Huma's been a reliable ear for Hil.

Kendall Jenner left her house Wednesday around noon to shoot 'KUWTK' scenes with her mom ... oblivious to the $200k nightmare she was about to endure.

Kendall and Kris Jenner headed into Whizin Market Square in Agoura Hills around 1:30 PM for lunch with Kourtney Kardashian -- just another casual day at the office.

That all changed about 12 hours later when, as TMZ first reported ... a bunch of her jewelry went missing from her Hollywood Hills home. Police believe it was an inside job.

Ivanka Trump had a fun night with Canadian Prime Minister and bae of the True North, Justin Trudeau.

Ivanka and Justin hit up "Come From Away" on Broadway Wednesday night. They arrived in separate cars, but in the same motorcade.

We hear it's a good show. Eyes on the stage, right?

Ben Affleck's support system is right in front of him ... literally.

Ben and Jennifer Garner were out Wednesday in Santa Monica just 1 day after Ben announced he completed rehab.

As we reported, their divorce is still full steam ahead ... but they are serious co-parents who not only get along ... they still support each other.

Several Victoria's Secret models are uniting for a common goal -- making the Miami beach even hotter than usual.

Taylor Hill, Romee Strijd, Elsa Hosk, Jasmine Tookes, Sara Sampaio, Josephine Skriver and others posed together in very tight formation ... all wearing white, lacy lingerie because ... why the hell not?

Kim, Kanye, Kourtney, Kylie, Tyga, Caitlyn and even reclusive Rob all did movie night Monday in the Valley ... the first time they've been all spotted together in public for a while.

Their film of choice -- "The Shack" -- about a man who loses his daughter and then gets an invitation to meet with God.

Eva Longoria can still flaunt what her mama gave her -- 42 years ago, mind you -- as seen from the front, back and side.

Yes, 2 days before her 42nd bday ... Eva blessed us doing a photo shoot in L.A. while sporting a couple of one-piece swimsuits, and some seriously badass stilettos.

Happy birthday, Eva! Thanks for sharing your gifts.
