Denise Richards and Richie Sambora are back together again.

The 41-year-old actress accompanied the rocker - whom she reunited with last November after splitting in 2007 before going their separate ways again in January - to the Midnight Mission's Golden Heart Awards at the Beverly Wilshire Hotel last night, where he was honored for his work with the Los Angeles-based homeless support and advocacy group.

Richie - who was also accompanied to the event by Ava, his 14-year-old daughter with ex-wife Heather Locklear - said, "We're back on. It's all good." Denise - who has three daughters, Sam, seven, and six-year-old Lola, with ex-husband Charlie Sheen, and adopted 10-month-old Eloise - was delighted to be giving her support to Richie because she is so proud of his efforts to help the homeless.

"This is a big night for Richie, so I'm here to support him. It's really important work that he does," she said.

When the couple separated in January, it was claimed they had decided they were better keeping their relationship on a friendship level. "They had a moment a few months back when they were going to give it a go, but have decided they're better as friends," a source said at the time.
