Billie Eilish goes Instagram official with her boyfriend Jesse Rutherford

Billie Eilish is showing off her boy. The singer, 20, gave followers a glimpse of her Halloween celebrations, posting a carousel of pics, including one of herself and her boyfriend Jesse Rutherford, 31. In the snap, Billie is dressed up as a baby with The Neighbourhood 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 Bad Guy singer captioned the post, "Life is craaaaaaaaaaaaaaazy. Happy Halloween." Billie and Jesse first sparked relationship rumours last month. 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.
