Heather Locklear and Jack Wagner have called off their engagement, their rep confirms.

The Melrose Place star, 50, and Wagner, 52, had been dating for four years and announced their engagement in August.

Just last night, Locklear walked the Twilight: Breaking Dawn red carpet without her engagement ring.

Locklear has been married twice before to Tommy Lee and Richie Sambora. She and Sambora are the parents to 13-year-old daughter Ava. Wagner was previously married to actress Kristina Wagner.
