Backlash be damned, she’s happier than ever.

Billie Eilish made her controversial relationship with her much-older boyfriend,

Jesse Rutherford, Instagram-official early Tuesday.

The “TV” singer, 20, shared a carousel of photos from her weekend of Halloween celebrations

including one of her and the Neighbourhood vocalist,

31, in costume as a baby and an elderly man, respectively

She also included a snap of Rutherford as a clown.

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

The new couple raised eyebrows on Sunday when they debuted their Halloween costumes at

a star-studded party, with Eilish wearing a bonnet

a bib and doll makeup while Rutherford sported a bald cap and a gray mustache.
