Kevin Costner during the 2025 Super Bowl – as her ex-fiancé, Don Jr. and his new beau, Bettina Anderson, also attended the big game.

Guilfoyle, who was with Donald Trump‘s son for more than six years, posted the picture on her Instagram Story before the game kicked off, as Costner seemingly put his arm around the socialite.

Guilfoyle looked trendy in a pair of red leggings, suede knee-high boots and a chic cropped black fur jacket.

It’s unclear exactly who Guilfoyle was rooting for, but red is the signature color of the Kansas City Chiefs, who are battling the Philadelphia Eagles for the Lombardi Trophy.

Her dark brown hair was loose in long waves, and she wore a neutral makeup look.

Costner, who stood next to her, kept it basic in a pair of tight khaki pants, white button down shirt and light brown suede boots.

However, Costner wasn’t the only celebrity that Guilfoyle spotted ahead of the game.

She also posed for photos with comedian Pete Davidson and actor Jaleel White, as well as Gracie Hunt, who is the daughter of Chiefs owner Clark Hunt.

But as Guilfoyle posed with Costner, her ex was also at the venue with his new girlfriend, socialite Anderson.

The couple attended the Fanatics Super Bowl Party at The Sugar Mill one day prior.

Taking to her Instagram Stories, Bettina gave a subtle shoutout to her beau Don Jr.’s dad, Donald, as she shared a snap showing off her outfit for the game.

‘Make bathroom selfies great again,’ she wrote, a spoof off Donald’s famous line, ‘Make America great again.

She donned a pair of dark jeans and a black blazer; she appeared to have nothing on underneath the jacket.

She left her long blonde locks in loose waves around her face and accessorized with a gold bracelet and necklace.

Don Jr. was at the Super Bowl, but was not pictured.

His father, Donald, was also in attendance with daughter Ivanka Trump, as he became the first sitting U.S. president to go to a Super Bowl.

However, although Guilfoyle and Don. Jr. broke off their engagement in late 2024, they appear to be amicable.

He exclusively told Page Six in December that he and Guilfoyle will ‘never stop caring for each other.’

‘Kimberly and I will never stop caring for each other and will always keep a special bond,’ the 46-year-old said in a statement.

Donald Trump even appointed Guilfoyle as the U.S. Ambassador of Greece.

‘I could not be more proud of her and the important role she’ll continue to play in my father‘s administration,’ Trump Jr. told Page Six.
