Rita Ora is certainly cheerful this holiday season!

The 26-year-old singer kicked off Love magazine's Advent calendar by rocking lederhosen and next to nothing during her sexy rendition of The Andrew Sisters' 1940s hit “Boogie Woogie Bugle Boy."

With a few costume changes, the star finished off the video by simply donning heart-shaped pasties on her breasts, between shots of herself flashing the camera.

The German-influenced outfits also included a pair of cheeky underwear with the word "Love."

The magazine's annual launch also featured Bella Hadid and Irina Shayk, but it was the singer's appearance that really stole the show.
