The mystery blonde spotted getting cozy with Kevin Costner has been unmasked as a glamorous lifestyle coach 31 years his junior - with a curious connection to the Hollywood star's sprawling Aspen retreat.
The Daily Mail can reveal Jennifer Milburn, 40, is the woman who accompanied the twice-divorced actor, 71, on a domestic supermarket run near his $145 million California compound earlier this month.
The two were seen stocking up on steaks, vegetables, grapefruit juice, and cereal at Albertsons in Santa Barbara - where onlookers described the pair as being 'extremely affectionate.'
And Milburn herself did little to quell speculation about the nature of her relationship with Costner.
When contacted by the Daily Mail, she confirmed her identity, but abruptly hung up when asked whether she and the Oscar-winner were an item.
Yet, despite being snapped together in California, it would appear it's a Colorado connection that may have brought her into Costner's orbit.

Milburn has her own connection to one of Costner's favorite haunts, having previously spent nearly six years working for western retailer Kemo Sabe in Aspen, according to social media
The Daily Mail can reveal Milburn has deep roots in the exclusive Rocky Mountain playground where Costner owns his spectacular 160-acre Dunbar Ranch.
Milburn - who is also a former Delta flight attendant - spent nearly six years working for celebrity-favorite western retailer Kemo Sabe in Aspen, has modeled for local brands, and even goes by '@theaspenjenn' on Instagram.
Social media also offers a glimpse into her part-time modeling career in the exclusive ski resort town, where she can be seen posing on horseback and sprawling ranches for a local jeans brand.
Currently, she has a remote position as director of partnerships for a firm called Simon Sinek's The Optimism Company, according to her LinkedIn profile.
Dubbed 'the ultimate luxury retreat', Costner's Dunbar Ranch is so vast it's been likened to a mini town. The property has 12 bedrooms and eight bathrooms, and can comfortably sleep 27 people.
He purchased the land in 2000 before transforming it into a picturesque paradise.
She also appears to have modeled clothing part-time for local businesses in the exclusive Rocky Mountains resort town, including being photographed at a ranch for a jeans brand
She also appeared in a catalog for pajamas for Aspen Dream brand
Milburn was seen getting cozy with Costner during a trip to Albertsons supermarket earlier this month
The television star is known to split his time between his homes in California and Colorado - where he has been seen mingling with other A-listers at glitzy star-studded parties over the winter holidays.
He was previously spotted enjoying drinks with Jennifer Lopez at hotspot Kemo Sabe - where Milburn once worked.
Costner's links to Milburn come after the twice-divorced Yellowstone star was reported last year to have quietly found love again with filmmaker Kelly Noonan Gores, in what sources described at the time as a 'private and casual' romance.
His apparent relationship with Noonan Gores, ex-wife of billionaire Alex Gores, was first revealed in August 2025 after the two spent time together in Aspen.
It was reported they met through mutual friends, with US Weekly quoting a source saying: 'After such a public and expensive divorce, he's being cautious.'
They 'see each other when schedules allow, often spending time at his Santa Barbara estate' and 'love dinners at home, walks on the beach and quiet nights in,' the source said at the time.
The pair were all smiles as they browsed the aisles together, with Milburn pushing their shopping cart

Another claimed that Costner was 'not looking for a serious relationship or marriage any time soon.'
Yet his recent outing with Milburn has now fueled fresh speculation that he has a new woman in his life.
Costner and Milburn were seen in exclusive Daily Mail photos getting cozy during the September trip to the supermarket.
They made no apparent attempt to keep the outing under wraps, with a casually-dressed Costner smiling alongside his female companion as she wheeled the cart around the store.
At one point, Milburn even took the lead by pointing out their preferences at a meat counter.
They were later seen headed back to Costner's gray Mercedes-Benz in the parking lot, where the actor dutifully returned the shopping cart.
Milburn previously worked at celebrity-favorite western apparel store Kemo Sabe, in Aspen, which Costner is known to frequent. He is seen in a photo posted by the business after one of his visits

Costner was previously linked to Kelly Noonan Gores (left) who was married to billionaire Alec Gores from 2016 to 2024. He was married to Christine Baumgartner from 2004 until their 2023 separation; pictured in March 2022. She has since moved on, marrying Josh Connor in October last year
Their brief supermarket sweep occurred only a few miles from Santa Barbara County Court, where Costner's bitter divorce battle with ex-wife Christine Baumgartner played out in 2023.
The divorce became final in February 2024 after an eye-popping battle over cash and assets.
The legal battle revealed astonishing household spending as Baumgartner, who filed for the divorce, at one point demanded $248,000 a month for support of children Cayden, now 19, Hayes, 17, and 16-year-old Grace.
Costner was ultimately ordered to pay Baumgartner, now remarried, $63,209 in monthly child support for their three children and $1.5 million to her personally.
Court documents also revealed Costner's Aspen compound cost $1,964,294 to operate in 2022.
The property has two large lakes and is equipped with a dozen ATVs and snowmobiles, which the children had enjoyed riding, the papers stated.
