Billie Eilish’s Christmas activities took a turn to the saucy side after recent snaps showed an inside peek at her celebrations, which included a very NSFW gift and a pair of cheeky hot pants.

The selfie showed Billie grinning as one of her friends placed the double ended object on top of her head. Eilish’s saucy snap cut off half her face and showed her smiling as she put one hand on her hip and looked through her fringe.

Another cheeky picture showed Billie playing Twister as she leaned over one of her friends and stuck her rear in the air. Eilish wore a pair of black denim trousers, black lace print tights and a black t-shirt as she laughed and beamed from ear to ear.

For a third picture, Billie held up a pair of red hot pants to the camera as she made a shocked expression. The Santa themed bottoms were trimmed with white fluff and held together with a black belt and a gold buckle.

Billie peeked over the top of the hot pants, clearly makeup free and looking naturally gorgeous with a Santa hat worn over her forehead.

She also added a video of a high energy Uno game played with pals, a Christmas tree with multicoloured lights, a happy birthday balloon, a picture of herself on the floor surrounded by shoes and a snap of Billie blowing out her birthday candles while celebrating on 18 December.
