Jane Seymour shares friendly kiss with hunky young musician -- who's not her boyfriend!

It's getting hot in here!

Jane Seymour stepped out for the Open Hearts Foundation's 2018 Young Hearts Spring Event in Malibu, Calif., on Sunday, and she shared a steamy moment with a hunky young musician who is definitely not her boyfriend.

The 67-year-old former "Dr. Quinn, Medicine Woman" actress was photographed locking lips with Irish musician Keith Harkin, 31, on the red carpet ahead of the event while wearing a light pink floral mini dress and matching pashmina.

Though the gesture definitely turned heads online, the kiss appeared to be thoroughly platonic, as Seymour attended the event with her boyfriend of four years, director David Green. Additionally, Harkin appears to be happily married himself, and he appeared at the Open Hearts affair with his wife, Kelsey.

Earlier this year, Seymour got people talking when she decided to pose for Playboy at the age of 67. Though the photos weren't nude, the stunt still made headlines for the British star.
