Billie Eilish has gone Instagram-official with her older boyfriend Jesse Rutherford, as she shared a picture of their "sick and twisted" couples Halloween costume.
The 20-year-old singer posted a series of snaps to social media from her spooky weekend, including one in which she posed next to the 31-year-old rocker.
For Halloween the pair seemed to make fun of their age-gap romance, with Billie dressing up as a baby and Jesse transforming into an old man.
