You'll never guess why Mila Kunis keeps her engagement ring from Ashton Kutcher locked away!

“My engagement ring is in a safety deposit box," the 32-year-old Bad Moms actress explained during an interview on the Australian radio show Kylie & Jackie O. "I'm like, ‘I can't wear this because someone's going to chop my hand off for it."

While Kunis keeps the 5-carat, Tiffany, solitaire diamond ring reportedly worth $250,000 hidden away, she still wears her thrifty $90 wedding band.

She and Kutcher chose inexpensive rings they found online for their Fourth of July wedding last year.

“I decided our wedding bands were going to be wonderful and beautiful and simple, and so we got them made on Etsy,” the pregnant star continued.

Kunis, who is mom to 15-month-old daughter Wyatt and is expecting her second child with Kutcher, recently shared the reasoning behind her budget bling during an appearance on Conan.

"I wanted the thinnest possible platinum band,” said the actress.“I was like, 'They're how much? What, this is astronomical!' So, I went on Etsy and I was like, '$90? Buy now!' Ashton's was $100, so technically his wedding band was a little bit more expensive.”
