Kevin Costner fangirled over by pinup January Jones after Sharon Stone recently ‘flirted’ with Yellowstone hunk

January Jones fangirled over Kevin Costner, 69.

On Sunday, the 46-year-old Mad Men actress took to Insta Stories to rave about her meeting with the Yellowstone actor.

They were at an event for Brunello Cucinelli at Chateau Marmont in Los Angeles.

‘Another wonderful evening with the incredibly warm family @brunellocucinelli_brand. And I finally met @kevincostner,” the single mother said.

Also at the event was Sharon Stone, who was seen chatting with Jones’ Mad Men co-star Jon Hamm.

And in an interesting twist, Costner and Stone, 66, were “openly flirty” at the 2024 Governors Awards at the Dolby Theater in Hollywood last month, sources told DailyMail.com.

“They started off politely with a chat and then he put on his Kevin Costner charm, you know, like the vibe he gave off in Bull Durham and Tin Cup, like heyyyy baby,” a witness told DailyMail.com.

‘Who knows if they went home together or even exchanged numbers, but it certainly seems like they really liked each other.

‘Sharon is such a class act, she handled the attention very well and was adorable. She winked at him and was sweet.”

This comes months after the Basic Instinct sex symbol publicly defended Yellowstone actor Costner during his divorce from Christine Baumgartner.

In 2023, Stone stood up for Kevin.

She claimed that her ex-husband, Phil Bronstein, “thought the same thing” as Costner’s estranged wife Christine Baumgatner.

Christine asked Kevin for $160,000 a month in child support after initially wanting $175,000 a month.

The Sliver actress shared the comment on an Instagram post. She added details about Christine’s day in court on August 31.

Christine talked about the lifestyle her children had become accustomed to with Costner, which seemed to irritate Stone.

Also at the same event was Sharon Stone. She was spotted flirting with Costner last month

Christine reportedly told the judge: ‘It’s so much more than this: it’s an experience. We have created a whole community,” she said.

They loved living together in Santa Barbara, where they said they played on the volleyball court, in the garden and in the infinity pool, she said.

On her behalf, her lawyers added that a life of luxury “is in their DNA at this point.” Responding to the claims, Sharon said: “My ex thought the same thing,” adding a laughing emoji.

Sharon married Phil, a San Francisco newspaper editor, in 1998, and they adopted their son Roan in 2000.

Phil filed for divorce in 2004 and was given custody of Roan in 2008.

The actress adopted two more children and years later Roan moved to Los Angeles to live with his siblings and mother.

It is not known what Sharon paid Phil.

Kevin and Christine married in 2004 and welcomed three children: sons Cayden, 16, and Hayes, 14, and 13-year-old daughter Grace.

Christine filed for divorce in May 2023 and they have been embroiled in a nasty lawsuit ever since.

Costner was in the news this year for not returning to Yellowstone.
