Denise Richards and Richie Sambora have gone public with their rekindled romance.

The on-off pair looked smitten with each other at an event in Beverly Hills last night. Denise was supporting Richie as he was honoured at the Midnight Mission's Golden Heart Awards at the Beverly Wilshire Hotel on Monday.

"This is a big night for Richie, so I'm here to support him. It's really important work that he does," Denise gushed to E! Online, before Richie smiled: "We're back on. It's all good."

Richie and Denise were also joined on the red carpet by Richie’s 14-year-old daughter Ava.

The 41-year-old actress and the Bon Jovi rocker dated from 2006 to 2007 after he split from his wife Heather Locklear and Denise had broken up from then-husband Charlie Sheen.

They sparked relationship rumours again after they were spotted hand-in-hand in Maui, Hawaii, at the beginning of last month.

The pair were joined by Denise's daughters Sam, eight, Lola, six, and baby Eloise, and Richie's daughter Ava.
