Internet ships Kevin Costner and Jewel as they indulge in PDA on Richard Branson's island

LOS ANGELES, CALIFORNIA: During their recent trip to the Caribbean, Kevin Costner was seen affectionately putting his hands around singer Jewel's waist, providing more proof that they are definitely dating.

Their time together over the Thanksgiving holiday at an event for Jewel's Inspiring Children Foundation on Richard Branson's Necker Island, provided ample proof the couple is apparently dating, as reported by DailyMail.

How many children does Jewel have? 

In a recent picture, the 49-year-old 'Who Will Save Your Soul' singer is shown smiling and being held by Kevin, 68, while she appears to be sitting on his lap and speaking into a microphone. 

She is seen smiling broadly as she addresses the assembly, clearly in high spirits in Kevin's embrace.

The singer and Costner took a joint flight to the Caribbean

Costner and the singer reportedly took a plane to the Caribbean together, spent more than a week hanging out, being 'flirty', according to TMZ.

'The Yellowstone' actor was at the island for a tennis fundraiser supporting Jewel, who co-founded the Inspiring Children Foundation. It was also said that after spending the day by each other's sides, they departed the event together.

'There was definitely something going on'

The site's source shared, "There was definitely something going on. They were flirty, and when they were together, it was like they both just lit up."

They also shared, "You could tell they were trying to be discreet, but anybody who saw them could tell something was going on."

The source for the website also revealed that Jewel has been "picky about who to date," but she approved of Kevin since she thought he "fits the bill."

She appeared to be traveling with her 12-year-old son Kase, who she has with her ex-husband Ty Murray, since he was spotted on the beach beside her in her Instagram pictures.

During the fundraiser event last week, Jewel made reference to Costner on her Instagram, stating that he was "kind enough to mentor our youngsters this year."

She added of the event, "Every year, my foundation and I go to Necker Island to help host a tennis event w Richard Branson to raise funds for our kids. Amazing players like come and support us in playing doubles with the folks who come. 

"It's an incredible time, and one I use to relax, rest and play w my son! and Sir Richard was his usual inspiring self- who also plays a mean game of doubles!"

Jewel and Costner were spotted having fun on the private island

Over the Thanksgiving holiday, Jewel and Costner were also spotted having fun on the private island with other celebrities like Emma Watson and Michael Bolton.

Jewel seems to be his ideal woman - young and blonde. In addition, he has dated blondes Elle Macpherson, Joan Lunden, Cheryl Teigs, and, of course, Christine Baumgartner, his former spouse.

When PageSix revealed in late November that Jewel and Kevin were traveling together, suspicions were aroused.

Costner seemed in high spirits and more interested in looking to the future than dwelling on his headline-making split from wife of 19 years Baumgartner, a source told the site.

As soon as the news of the couple went viral fans expressed thier views.

One of the user wrote, "Did not have Jewel + Kevin Costner on my bingo card, but here we are." Another user penned, "Not one to typically care about celebrity gossip, but I’m so here for the Jewel and Kevin Costner romance. #jewel #kevincostner"

The third user chimed in, "Now there is a pairing I didn't see coming! Cute! Kevin Costner and Jewel Dating, Cozy Photos on Caribbean Vacay."
