LOS ANGELES -- Actor Gary Coleman got married last year but he's only revealing it now.

Coleman said that he and Shannon Price exchanged vows in August on a mountaintop in Nevada.

"Nobody was around but the minister, preacher, the videographers, the photographer, the helicopter pilot and us," Coleman and Price told "Inside Edition" in the first of a two-part interview. The second segment airs Wednesday.

Coleman, who's 40, met Price, who's 22, on the set of the 2006 comedy "Church Ball." The actor is 4-foot-8 and Price is 5-foot-7. But Coleman's new bride insists height doesn't matter.

"He was 10 feet tall to me because he was sweet and I really liked his personality," Price told Inside Edition. "That doesn't really matter to me."

Price said that she proposed to Coleman, but he surprised her on her birthday by taking her to a mountaintop in the Valley of Fire State Park in Nevada to exchange vows.

Coleman rose to fame as a child actor in late 1970s and 80s as the precocious Arnold Jackson, the adopted son of Philip Drummond (Conrad Bain) on the hit sitcom "Diff'rent Strokes."

Coleman told "Inside Edition" that his union with Price is his first "romantic relationship."

"I never got the opportunity to be romantic or feel romantic with anyone ... I wasn't saving myself, she just happened to be the one," Coleman said.
