Billie Eilish makes romance with 'much-older boyfriend' Instagram official

Billie Eilish has made her relationship Instagram official on Halloween.

The 20-year-old singer turned to the social media platform in Tuesday to share a thread of photos and videos with beau Jesse Rutherford, 31.

“life is craaaaaaaaaaaaaaazy happy halloween,” Eilish captioned the post.

For the spooky night, Eilish wore a bonnet, a bib and doll makeup. Rutherford, on the contrary, sported a bald cap and a gray mustache.

Fans were quick to comment on the pictures, as they mocked the singer for dating an older guy. 

"Can’t believe billie eilish and jesse rutherford didn’t dress up for halloween,” one fan tweeted, poking fun at the pair’s 10-year age gap.

“Billie is grown enough to know how weird and creepy this is,” another wrote.
