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.
Billie wore a blonde wig and an outfit emblazoned with teddy bears. She also opted for creepy doll-like makeup and wore a pair of pink rabbit slippers.
Jesse sported a bald cap complete with grey tufts of hair and also dyed his moustache and eyebrows grey.
Captioning her Instagram post, Billie wrote: "Life is craaaaaaaaaaaaaaazy happy halloween."
Fans offered their opinion on the snap, with one person writing: "That last slide is gonna haunt her in a few years when she’s older and realises that a 31 year old has no business with someone that young."
Another said: "NOT THE BABY AND THE GROWN MAN GIRL DELETE THIS."
"Strange costume idea," commented a third.
The couple "disturbed" fans on Monday when they debuted their Halloween costumes at a star-studded party.
One person tweeted: "That Billie eilish costume is extremely disturbing and i absolutely hate it everytime it crosses my timeline."
"She's of legal age and all but this couples costume feels uncomfortable.," another said, while a third person tweeted: "I wish I could wash my eyes with soap and scrub this from my mind."
"Billie Eilish and Jessie Rutherford’s matching Halloween costumes is incredibly sick and twisted - especially with their age difference and power imbalance.
"It’s not funny or chic, its not poking fun, it’s disturbing, and the adults in her life are letting her down once again," another penned.
Some fans saw the funny side of their costumes, with one person tweeting: "I have ALWAYS 'LOVED'@billieeilish sense of humor. This shows her as she is, HILARIOUS ! All you silly people need a sense of Humor. Love it Billie."
"I mean they’re trolling the people that are having a unnecessary opinion about their relationship. So In a way ur proving their point and making their joke even funnier," another said.
A third fan added: "She's 20 already, a whole adult, how is this weird?"
Billie and Jesse went public with their romance last month, when they were pictured kissing outside an Indian restaurant in Los Angeles.
