Bridget Marquardt Is Engaged, Shows Off Giant Diamond Spider Ring

By
Bridget Marquardt is taking her self-proclaimed Twitter title of "Queen of Halloween" to a whole new level.
The ex-girlfriend of Hugh Hefner announced her engagement to longtime boyfriend Nick Carpenter over Instagram on Thursday. In the pic, Carpenter and Marquardt, who met at the Playboy Mansion and have been dating since 2008, are holding hands, showing off an extremely unique engagement ring -- a diamond encrusted spider. A sign that reads "Till Death Do Us Part" is pictured in the background.
"Happy Oct. 1st!!! Oh...and... Did I mention @nicholascarpenter and I are engaged?," the 42-year-old Girls Next Door star wrote.

Though it hasn't been confirmed whether the jewelry is her actual engagement ring, it wouldn't be that surprising, seeing how Halloween-obsessed Marquardt is in real life. Marquardt frequently posts about her favorite holiday on her social media accounts. Most recently, the TV personality shared photos from her Halloween-themed Disneyland trip with former Playmate Holly Madison and friend Ashley Matthau.
"Haunted Mansion leggings for my spooky Disney trip with @ashleymatthau & @hollymadison," she captioned the pic.
It wouldn't be a true Disney trip without riding the Hollywood Tower of Terror.
"One of my faves," the actress captioned the pic of her sitting without her besties on the ride.
The girls even got honorary death certificates.
"We got Haunted Mansion death certificates! Woo hoo!," Matthau shared.
Later, the three girls sipped on poison apple martinis.

Turns out, the trip was all in celebration of Marquardt's exciting news.
"Congratulations @Bridget on your engagement," Madison tweeted with a pic of the same drinks immediately after news of her friend's engagement broke.
While Madison may be on good terms with Marquardt, her relationship with another former Playmate, Kendra Wilkinson, has gotten ugly. In a promo clip for Kendra on Top, Wilkinson claims that Madison wrote "disgusting" lies about Hefner in her tell-all memoir, Down the Rabbit Hole: Curious Adventures and Cautionary Tales of a Former Playboy Bunny.
