"6 years down a lifetime to go!" the actress wrote on Instagram.

— -- Beth Behrs and Michael Gladis are engaged.

The couple has been together for six years, she added.

"Thank you also to my beautiful friends and family! Can't wait to celebrate!" she wrote next to a collage of photos.

Behrs, 30, seemed to know last year that Gladis, 38, was "the one." In an interview with People, she demurred when asked if an engagement ring was in her future, but acknowledged that her love life was in a good spot.

"I've been in the same relationship for five-and-a-half years. He's the best," she said.
