Kevin Costner and singer Jewel ignited romance rumors last week when they appeared together at a charity event in the Caribbean, and it appears they can thank Richard Branson for playing matchmaker.

The pair were photographed 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.

According to sources in The Daily Mail, "Richard is 100 percent responsible for Kevin and Jewel hooking up. She has been a friend of Branson's for years and he has been a close friend of Kevin's since the 1990's."

"Richard invited Jewel to hold her charity fundraiser on Necker and, honestly, the hookup happened organically," the source continued. "They hit it off well and Jewel seems to be happy about it."

A representative for Branson told Fox News Digital that they have no comment at this time. Representatives for Costner and Jewel did not immediately respond to Fox News Digital's request for comment.

The outlet’s source said Branson invited Costner to his luxury Necker island to help distract him from his contentious divorce from his ex-wife Christine Baumgartner, while at the same time inviting Jewel to the island for her fundraiser.

Costner finalized his divorce from Baumgartner in September, after 18 years of marriage and three children, settling just before they were due back in court to establish who would be responsible for paying Baumgartner’s nearly $1 million in attorneys’ fees.

Costner has previously been married, first to Cindy Silva from 1978 to 1994, and they had three children together. The "Dances with Wolves" star is also a father to a son with Bridget Rooney.
