Kevin Costner and singer Jewel are sparking romance rumors after appearing together at a charity event in the Caribbean.
Photos obtained by TMZ show Jewel speaking into a microphone and appearing to sit on Costner’s lap, with his arms around her waist.
The two were on Richard Branson’s Necker Island in the British Virgin Islands for a tennis fundraiser for the Inspiring Children Foundation, an organization started by Jewel.
Sources told TMZ the pair had flown to the Caribbean together, and hung out longer than the event, saying, "There was definitely something going on. They were flirty, and when they were together, it was like they both just lit up."

Representatives for both parties did not immediately respond to Fox News Digital’s request for comment.
Earlier this year, Costner finalized his divorce from his wife of 18 years, Christine Baumgartner, with whom he has three children.
Baumgartner filed for divorce on May 1 citing irreconcilable differences. In documents obtained by Fox News Digital, Christine cited April 11 as the date of separation.

She initially requested $248,000 in monthly child support for their three children, and a judge set a temporary monthly sum of $129,755 in July, only to rule in September that Costner would actually be responsible for $63,209 in monthly child support payments.
After a contentious four months in and out of court over child and spousal support payments, the former couple settled their terms in September, shortly before they were due back to establish who would be responsible for paying Baumgartner’s nearly $1 million in attorneys’ fees.
