Glanville is a former model whose ex-husband, actor Eddie Cibrian, left her for married country music star LeAnn Rimes in 2009. After divorcing their respective spouses, Cibrian and Rimes married last April.
Glanville announced via Twitter Sunday she had tied the knot with Harvey in Las Vegas, UsMagazine.com reported.
"I'm married again ...," she said, describing Harvey as her "best friend" and proclaiming herself an "official housewife, for reals."
However, Harvey dismissed the wedding as "a drunken ... thing" in his own Twitter posting Sunday.
"I had a crazy Vegas moment," UsMagazine.com said he wrote. "Getting annulled tomorrow."
