Billie Eilish goes Instagram official with boyfriend Jesse Rutherford

Billie Eilish has taken her new romance to Instagram! The Bad Guy singer, 20, gave followers a glimpse of her Halloween celebrations, posting a carousel of pics, which included a snap of herself with boyfriend Jesse Rutherford, 31.

In the snap, Billie is dressed up as a baby with The Neighborhood vocalist donning an elderly man costume -- poking fun at their age difference that has made headlines in past months. Other photos featured herself carving a pumpkin, Dylan Minnette as a pumpkin and Jesse as a clown. 

The Happier Than Ever songstress captioned the Oct. 31 post, "life is craaaaaaaaaaaaaaazy. happy halloween." Check out the post below!

Their outing came just a week after an Oct. 15 TikTok video showed the pair holding hands at Universal Studios' Halloween Horror Nights. While this Halloween marks the first time Billie has publicly posted about her new man, she and Jesse have reportedly been friends for years.
