Kevin Costner and Jewel are enjoying a flirty relationship. Here are the other new couples closing out 2023 together.

This has been quite the year for high-profile breakups, but it seems a lot of stars are closing out 2023 with new relationships.

Kevin Costner and Jewel sparked dating rumors after they were pictured getting cozy in the British Virgin Islands last month. The Yellowstone star, 68, attended Jewel's Inspiring Children Foundation's tennis fundraiser, which took place on Richard Branson's Necker Island. TMZ obtained an image of the 49-year-old singer sitting on Costner's lap.

"It's very new," one source tells Yahoo Entertainment, noting the pair has "mutual" interest is in each other as they are in the "early stages" of talking.

"They enjoyed spending time together," adds the insider. Reps for the pair did not respond to Yahoo's requests for comment and neither star has commented on dating speculation. However, Jewel did give Coster a shout-out in November while discussing her foundation.

TMZ reported on Friday that Costner and Jewel traveled together to the Caribbean, where they hung out for more than a week. "There was definitely something going on. They were flirty, and when they were together, it was like they both just lit up," a source claimed. "You could tell they were trying to be discreet, but anybody who saw them could tell something was going on."

According to a new report on Monday, it was Branson who allegedly played matchmaker by inviting them both to the island. This is the first woman Costner has been linked to since finalizing his contentious divorce from Christine Costner (née Baumgartner). As for Jewel, she divorced ex-husband Ty Murray, a professional rodeo cowboy, in 2014.

It's been a busy week for new (or maybe/sorta) couples in Hollywood.

Selena Gomez and Benny Blanco

Last week, the Rare Beauty founder finally commented on her relationship status — and much to the dismay of some Selenators — she professed her love for Blanco.

"He is my absolute everything in my heart," Gomez said on Instagram to one commenter. The singer was very active for a few hours, replying to multiple people who seemed to disapprove of Blanco as a romantic partner. Gomez called him "the best thing that ever happened to me" and "better than anyone I've ever been with." She also shared a picture wearing of herself wearing a "B" ring.

Perhaps Gomez was inspired to go public with Blanco, whom she said she's been with for six months, by bestie Taylor Swift. Last week, Swift shared why she's not hiding her relationship with boyfriend Travis Kelce. ("Life is short," she said as Time's Person of the Year. "Me locking myself away in my house for a lot of years — I'll never get that time back. I'm more trusting now than I was six years ago.")

Blanco left a flirty comment on one of Gomez's Instagram posts over the weekend, dropping a heart-eyes emoji on her carousel of photos.

Lupita Nyong'o and Joshua Jackson

Days after Jackson and the Oscar-winning actress went to great lengths to hide that they were grocery shopping together, the two were photographed walking hand-in-hand while visiting Joshua Tree, Calif. Fans have been curious for a while about what's going on between the actors.

Two months ago, the Dawsons Creek alum's wife, Jodie Turner-Smith, filed for divorce, which purportedly shocked the actor. Weeks later, Jackson and Nyong'o were publicly linked for the first time. (Around the same time, the actress confirmed her split from musician and sports commentator Selema Masekela.) Neither Jackson nor Nyong'o has commented on their new relationship.

Sophie Turner and Peregrine Pearson

The Game of Thrones alum was spotted kissing Pearson in public for the second time since October. Turner and Joe Jonas were at odds earlier this year amid their nasty divorce, but ultimately hashed things out in mediation.

"Sophie has been casually dating a few people since her split from Joe," an insider claimed to Us Weekly, adding that Turner "really seems to like spending time with Perry."

The two have "become progressively closer" as of late. "Things are still fairly new," the source added. "But she's really happy with how things are moving along."

Joe Manganiello and Caitlin O'Connor

Manganiello has officially moved on from Sofia Vergara. It was revealed in July the actors were divorcing after seven years together, and last week, Maganiello made his red carpet debut with O'Connor. Manganiello and the Winning Time: The Rise of the Lakers Dynasty star attended an event together in New York, seemingly confirming earlier reports that they are seeing each other. (Meanwhile, Vergara has been dating orthopedic surgeon Justin Saliman.)

Jeremy Allen White and Rosalía

The Bear star and Rosalía were linked in November amid his divorce from Addison Timlin — and they've wasted no time fueling romance rumors. White and the singer were photographed holding hands in front of paparazzi earlier this month, and a new report lifted the lid on their purported steamy romance.

"They started as friends, but things turned romantic," one insider told Us Weekly, adding that White likes the singer's "style and intellectual savvy" while Rosalía enjoys his "easygoing" personality.
