The 54-year-old actress and plastic surgeon Marc Mani dated for more than three years, but they ended their relationship just before she posted a series of throwback photos of her ex-husband, Motley Crue drummer Tommy Lee.
"He isn't even quite sure what those Tommy Lee pictures were all about," a source close to the situation told RadarOnline.com about the strange pictures.
In the first photo posted on May 10, 2016, Locklear and Lee are tongue kissing and she captioned the photo "Happy 30 years baby."
The second is a picture from their wedding.
