AceShowbiz - Miley Cyrus stripped down to her undies in a new Tik Tok video. The 26-year-old singer/songwriter flaunted her slim figure in a black lacy bra and a pair of silk boy shorts as she danced with her 22-year-old boyfriend Cody Simpson.

The blonde stunner and her Aussie beau showed off their coordinated moves, grooving to Ashnikko's catchy song called "Stupid". The video, that saw Cody dressed in all-black as well, seemed to be taken in the bathroom.

Miley and Cody recently celebrated Halloween at Universal Studios' Horror Nights. They were joined by their friend Jeremy Scott and she posted several pictures from the trip. "Scared AF clinging to @itsjeremyscott all night!" she wrote in one of her posts.

She additionally uploaded a slew of pictures showing her dancing with a skeleton. She mocked the media's exaggerated stories about her as she penned in the caption, "Me when : 'Onlookers report Cyrus was seen dancing the night away with mystery dead man. The two looked happy and very much in love. At one point he was seen cheekily lifting up her skirt which led to the couple sharing a very public kiss! She's just being Miley.' "

Miley Cyrus and Cody Simpson kept going strong despite recent reports that he complained about the drama surrounding their relationship. The two have been friends for a long time before they dated following her split from husband Liam Hemsworth and her separation from love squeeze Kaitlynn Carter.

In an interview, Cody confessed that Miley was his childhood crush. He adorably admitted to kissing the former "Hannah Montana" actress on TV screen when he was young. He also helped nurse her back to health during her recent hospitalization and defended her when she landed in hot water for seemingly suggesting that sexuality was a choice.

Their romance has got a stamp of approvals from both of their mothers.
