Glanville, 38, tied the knot with Darin Harvey, a mixed martial arts manager, after a tequila-filled night in Sin City, according to her Twitter feed.
She also posted a picture of the nuptials on Twitter, with the caption, "It wasn't planned and we will handle it, but good times!"
"I'm married again - suuuuuuck it!" she further Tweeted.
The newlyweds celebrated their "honeymoon" later in the evening at the strip club Spearmint Rhino.
But the marital bliss was short-lived. The couple plan to have the union annulled, Harvey Tweeted Monday, characterizing the wedding as a "drunken BFF thing."
"It[']s not legal! We were just having fun!," Glanville Tweeted.
Apparently not everyone saw the humor, however – some of Glanville's Twitter followers criticized the stunt.
"I didn't mean to offend anyone!" Glanville responded. "I believe everyone shud [sic] be able to get married & maybe even embarrass themselves in Vegas ;)."
Seems like those quickie Vegas weddings just don't last.
