The TV presenter and model married New Kids on the Block star Donnie Walhberg on 31 August but, less than a fortnight later, she's no longer sporting a blinging diamond on her finger after misplacing the rock during a night of passion at a hotel.
Jenny told Good Day NY: "We were staying in a hotel and you can't have a wedding ring on… it's a little hard to get romantic with diamonds on your hand. I removed it and put it on the room service table and they came and turned down the room and the ring was gone.
"But you know what though? If you're gonna lose your wedding ring, you should lose it that way."
She added to ABC News that she was hoping someone found her ring soon.
"They could have maybe not seen it, or it could have gone under a dish and thrown away on accident. I keep going, 'Where is my ring?!' But Donnie and I are both laughing that at least we lost it for the best reason possible!"
Jenny – who is mum to son Evan, eight, - married Donnie, a dad of two, in a small ceremony outside of Jenny's hometown of Chicago, Illinois on 31 August. They'd been engaged for four months.
Unfortunately, Donnie's famous brother Mark was unable to make the nuptials as it was the same day as his daughter's birthday in LA, but he tweeted: "I love you, Donnie, we're very happy for you. Sorry we couldn't be there, we'll see you soon."
Jenny was previously in a long-term relationship with Jim Carrey.
