Flashback! Meet the '80s Stars on Tonight's 'RHOBH'

On tonight's episode of The Real Housewives of Beverly Hills, Kim Richards had the ultimate flashback to her days as an '80s child star: she attended the Hollywood Show, where she basked in the love of (and signed a few head-shots for) her most loyal movie fans.

She was also in the company of many of her childhood acting peers. And we were surprised to see many of our favorite cult movie stars making comebacks on the small screen. Ever wonder what happened to the star of the '80s b-movie Pumpkinhead II? And what are R&B singing sensations Marylyn McCoo and Billy Davis Jr. up to these days? Read on to find out.

Ami Dolenz
She was credited on the show for her starring role in Pumpkinhead II, but the actress has had prominent roles in other '80s classics like She's Out of Control (opposite Tony Danza) and Can't Buy Me Love. These days, Amy lives part-time in Los Angeles and Vancouver B.C. with her husband, actor Jerry Trimble. She's also dabbled in writing children's books, including this year's Harold and Agatha: the Mysterious Jewel. On the side, Ami sells vintage goods on her eBay boutique, Bluebell.

Marilyn McCoo and Billy Davis Jr
You may not know their names, but you definitely know their work. McCoo and Davis were founding members of the soul-jazz group the 5th Dimension, best known for their treacly '70s hit "Aquarius/Let the Sunshine In" (That's the one that goes, "This is the dawning of the age of Aquarius...age of Aquarius!") The couple, who became born again, have been married for over 40 years and credit their faith with their long-lasting marriage and careers: "We couldn't have done it without the Lord, because we truly had our struggles and we've worked through them," McCoo recalled in 2009.

Diane Franklin
Who can forget the actress who starred as foreign exchange student Monique opposite John Cusack in 1985's Better Off Dead? Though she retired from acting in 2006, she's revived her career with a series of roles in short films like 2013's Lovechild. She's married with two children to writer and producer Ray DeLaurentis.

Richard Chamberlain
The actor was a teen idol in the '60s thanks to his role on the television show Dr. Kildare. He also had successful strings in mini-series like Shogun and the Thorn Birds and had the starring role in the television film version of 1988's The Bourne Identity. In his 2003 memoir Shattered Love, Chamberlain, now in his 70s, opened up about his homosexuality and played the role of an HIV-positive man on ABC's acclaimed series Brothers and Sisters.

Jimmy McNichol
The brother of actress Kristy McNichol, Jimmy was an '80s heartthrob thanks to shows like Little House on the Prairie and the Fitzpatricks. He also caught the eye of our fair RHOBH star and Kim opened up about her crush on tonight's episode. "He was on the cover of every magazine," she gushed. "He was the Jonas Brothers."
