Nicole Richie's engagement joy
The daughter of singing legend Lionel Richie, who has been dating the DJ for over a year, was said to be thrilled when Adam popped the question.
No date for the wedding has been decided although it is set to be a lavish affair with guests including Nicole's 'Simple Life' co-star Paris Hilton, teen actress Lindsay Lohan and Paris's sister, Nicky.
Last year, Nicole claimed she was still a virgin.
Despite her colourful past, which included a drink and drug addiction, the reality TV star insisted she had never made love.
She confessed: "I'm a virgin. If Britney can say it, I can say it."
Although Nicole, 23, has had several boyfriends in the past - she claimed Ozzy Osbourne's eldest daughter, Aimee, always tried to steal them from her.
She told America's Stuff magazine at the time: "She has a habit of going after every guy I was involved with."
The star also admitted that she has a pierced nipple - but she won't let anybody touch it.
She explained: "My hair has snapped on it before and it hurts."
