Lorenzo Lamas marks Heather Locklear’s 65th with a wedding-cake joke

Lorenzo Lamas marked girlfriend Heather Locklear’s 65th birthday on Sept. 25 with an Instagram photo of them cutting her cake. He called her his “Queen” and joked it was the only cake they’d cut together, seemingly referring to a wedding cake.

Locklear had called Lamas her “new boyfriend” during an early-June appearance on the Hollywood & Divine podcast and said she was in the best time of her life. A friend of Locklear’s had confirmed their relationship to PEOPLE nearly six months before the birthday post.
