Los Angeles: Actress Denise Richards has reportedly parted ways with singer Richie Sambora again.

The couple, who rekindled their romance last November following their break-up in 2007, has decided once more to call time on their relationship as they think they are better off as friends.

"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," source said.

Richards, who has three daughters Sam, seven, and six-year-old Lola, with ex-husband Charlie Sheen, and adopted six-month-old Eloise has always had feelings for Sambora and said he would always play a part in her life.

Writing in her memoir, Richards said: "Richie and I shared an easiness I hadn't before had. We were able to be open, honest, and completely authentic with each other, with no judgement."
