The former child star was chatting about her upcoming marriage to actor Liam Hemsworth with U.S. TV host Ellen DeGeneres when a light bulb appeared to blow in the studio.
Two overall-clad 'engineers' then walked onto the set and gave Cyrus a shock by showering her with dollar bills, ripping off their T-shirts, and gyrating in front of her - giving the star a taste of what her bachelorette party might look like.
As she giggled and repeatedly squealed "Oh my God!" and "Hell yeah!", one of the men wrapped his torn top around her neck and playfully tried to pull her head towards his groin before Cyrus slapped his butt three times with her hand.
As the two strippers left the set, they gave Cyrus a kiss on the cheek and one of them told her, "You're beautiful" prompting the star to reply, "Thank you... Do I get to keep the money?!"
The TV moment will air in the U.S. on 8 November (12).
