Kevin Costner is flexing his status after his ex-wife got engaged to a former friend of his … getting the royal treatment in New Orleans for Super Bowl LIX.

The “Yellowstone” star is enjoying the Crescent City before Sunday’s big game, riding a pedicab through the streets.

Looks like Kevin’s joining the growing list of celebs in town to see the Kansas City Chiefs take on the Philadelphia Eagles in the year’s biggest sporting event.

LiAngelo Ball is dealing with some baby mama drama … the mother of his 2 children claims he is walking out on their family after getting another woman pregnant and starting a new life with her.

The “Tweaker” rapper and basketball player has two kids with Nikki Mudarris … and the reality TV star claims LiAngelo just confessed to cheating on her.

Nikki says … “I see everyone has been sending me @gelo cheating on me. I want to clear this up and speak my truth. I am just as surprised as you are. We spent 3 1/2 years together, and last week he decided to walk out on his kids and tell me he got someone else pregnant (allegedly) and now is creating a new life with her.”

Nikki adds … “The ultimate betrayal is not even the word. My daughter is not even 2 months old, and dealing with this and postpartum is very hard. Please pray for me and my healing because I will get through this. I have to be strong for my kids, but I have absolutely no words.”

She also takes some shots at LiAngelo … “Karma is real and God don’t like ugly. I hope it was worth losing his family.” She says LiAngelo confessed to cheating in a text, blasting him as a “coward” and “pathetic.” She has since gone on her stories to claim he broke the news to her via text.

LiAngelo’s rap career is blowing up thanks to his “Tweaker” success … and he’s just been tapped to perform at the upcoming NBA All-Star Game.

Unclear who LiAngelo’s new alleged chick is, but Nikki says the woman is older than her. Nikki also has a message for LiAngelo’s new flame … “The same way you get them is the same way you lose them, thinking you winning by getting pregnant with a man who has a newborn is crazy work.”

“Survivor” villain Jonny Fairplay‘s grandmother is dead … and this isn’t another elaborate hoax to gain an edge.

The reality TV star tells TMZ … his grandma, Ellen Jean Hauser, died Friday at Embrace Hospice House in Myrtle Beach, South Carolina. The cause of death was kidney failure.

Jonny infamously lied about his grandma dying way back in 2003 on “Survivor: Pearl Islands” to advance on the show … with the cast only finding out he was fibbing until the show was done filming.

“Survivor” host Jeff Probst has called it “the greatest lie in ‘Survivor’ history” … ripping Jonny for being, in his estimation, “completely despicable” and “an absolute jackass.”

Jon says his grandma leaned into the lie in real life, with a “Dead Grandma” vanity license plate.

Ellen had 7 husbands and Jon says she dated country star Faron Young and had a fling with singer/actor Robert Goulet.

Jonny tells us … “I’ll miss her every day. It’s easy to think she was just part of one of the biggest lies in TV history, which made me famous, but I look at her place in my life as a loving grandparent who only wanted the best for me in my life and she’d do anything to help me get it, which she did.”

Fairplay adds … “Her dying words were something like, ‘Jonny I want to see you on ‘Survivor 50,’ ‘Traitors’ and ‘Deal or No Deal Island.’ I had no idea she had so many streaming services.'”

She was 90.
