Dallas Cowboys superstar Dak Prescott and his fiancée, Sarah Jane Ramos, are not getting married — TMZ Sports has learned the two have broken up one month before their wedding.

We’re told the relationship had been rocky behind the scenes for months … but things came to a head with a blowup argument at their joint bachelor and bachelorette parties in the Bahamas — and Sarah Jane called it off.

She actually shared several snaps from her bachelorette party with her closest friends earlier this week … captioning the post, “I truly believe you can get through anything in life as long as you have really great friends. I love these girls so much.”

The reality is, we’re told the relationship is beyond repair … so the focus will be on coparenting their two kids — ages 2 and nearly 10 months — moving forward.

Southwest passengers had to make a detour for a security-related issue … which ended with cops rushing onto their plane guns blazing.

Video is circulating online that captured the moment that went down Friday … after a flight leaving Nashville for Fort Lauderdale had to divert to Atlanta.

Check out the clip … multiple officers outfitted in full tactical gear head down the narrow aisle way toward the back of the plane — before wrenching a man out of his seat and slapping cuffs on him.

The company lauds its flight crew’s response to the incident and apologizes to the passengers for the significant delay.

Southwest tells us customers were put on another aircraft, which continued on to Fort Lauderdale. They landed around 3:30 AM.

Devon Windsor is seriously hot … so it’s no surprise she made it big as a top model — and we’re taking a look back at some of her best shots as she celebrates her 32nd birthday!

The birthday babe clearly has that bikini body on lock, regularly sharing sun-soaked snaps from dreamy destinations all over the globe.

Devon’s got the posing game mastered too — whether she’s adjusting her swimwear, lounging poolside, or running a hand through her hair — the model knows exactly how to work her angles and is teasing that she’s only getting hotter with age!

Corey Parker — a longtime actor who appeared in numerous well-known shows and movies — has died … TMZ has learned.

Emily Parker — Corey’s aunt — tells us the star passed away Thursday in Memphis, Tennessee after a battle with cancer. It’s unclear what type of cancer he had.

Corey got his start in the film industry in the mid-1980s … notably winning the role of Pete in “Friday the 13th Part V: A New Beginning.” He followed that up with a small part in the Kim Basinger romantic drama “9 1/2 Weeks.”

In 1992, Corey landed a starring role in the sitcom “Flying Blind” alongside Téa Leoni. He played Neil Barash — an awkward college grad who begins dating Leoni’s wild and free Alicia.

Lisa Kudrow, Peter Boyle, Andy Dick and Noah Emmerich all appeared on the show during it’s one-season run.

“Will & Grace” fans may remember Corey for his recurring part as Josh — one of Grace’s boyfriends — in five episodes of the hit sitcom.

His other credits include … “Biloxi Blues,” “White Palace,” “Love Boat: The Next Wave,” “Nashville,” and “Blue Skies.” In his later years, Corey transitioned to working as an acting coach … providing advice on the shows “Sun Records” and “Ms. Marvel.”

BGB Studios — an acting studio which Corey was involved with — also posted in his honor … sharing a loving tribute to the now deceased star.

And it appears Corey grew up in a very creative family … his mother, Rocky — who was married to Patrick Dempsey in the late ’80s and early ’90s — and his sister, Noelle, were both actors, too. Rocky passed away in 2014.

Corey was 60 years old.

Kevin Costner‘s used to dancing with wolves, but on Friday night he was chatting with a stone-cold fox … leaning in for a convo with Brooks Nader.

The actor and the model both attended a VIP dinner hosted by Scott Sartiano — the owner of the popular NYC social club Zero Bond — at his restaurant Sartiano’s in the Wynn Hotel and Casino in Las Vegas to celebrate the opening of Zero Bond Las Vegas.

Eyewitnesses tell TMZ … Costner and Nader were spotted chatting it up at dinner and hanging out in the high roller room of Zero Bond, where attendees played their choice of roulette, blackjack or poker.

They were far from the only famous faces who attended the dinner … Gwyneth Paltrow, Orlando Bloom, Ryan Phillippe, Corey Gamble, Crayton Carrozza, Rachel Zoe, Jon Hamm, Jeffrey Beacher, Ashley Benson and many more stars also attended.
