A source confirms to PEOPLE that Mel Gibson has struck up a romance with a young film writer who also happens to be a champion equestrian vaulter.
Gibson, 59 and Rosalind Ross, 24, recently spent time together at his Costa Rica compound.
Ross, who won a gold medal at the World Equestrian Games in Kentucky in 2010, is also a budding screenwriter. She studied writing and literature at Emerson College and is currently one of the writers of the El Rey Network s action series Matador.
In 2011, Ross posed au naturel (along with equestrian partner Devon Maitozo) for ESPN Magazine’s 2011 Body Issue.
According to The Hollywood Reporter, Ross also recently wrote the script for the upcoming film Lioness, an indie drama staring Ellen Page.
Gibson, has kept a low romantic profile in the media since ending his rocky relationship with Oksana Grigorieva with whom he has a 5-year-old daughter.
