Cody Simpson, Miley Cyrus passionately kiss in Halloween costumes

Miley Cyrus and her new flame, Cody Simpson, have gotten hot and heavy for Halloween - and shared it all over social media.

Miley Cyrus and Cody Simpson put their romance out there on Halloween.

The couple, who dressed as Billy Idol and his ’80s flame Perri Lister, flaunted their PDA on Instagram in various videos that showed them making out and intimately dancing to Idol’s hit song White Wedding.

Cyrus, 26, helped transform the 22-year-old Australian crooner into the British rocker, captioning a series of photos that showed off the makeover, “makin up my man into baby billy idol!”

Cyrus captioned another series of photos that showed off their looks, “BILLY F – KIN IDOL LOVES PERRI F – KIN LISTER.”

The costumes even caught the eye of Idol himself. The 63-year-old gave his stamp of approval, sharing the couple’s photo on his Instagram page and writing, “Trick & Treat! Cheers Miley & Cody Repost @mileycyrus -BFI.”

Simpson and Cyrus’ relationship escalated quickly after she split from Kaitlynn Carter, following her separation from Liam Hemsworth.

The singer and Hemsworth’s divorce is ongoing.
