The “Bad Guy” singer – who turned 21 on Sunday – posted several photos from her A-List event, which featured boyfriend Jesse Rutherford by her side throughout the night.

The lovebirds shared several smooches in front of guests before a DJ told everyone to put their “motherf–king hands in the sky” and toast to the birthday girl.

Rutherford, 31, and Eilish were fittingly dressed as Mr. and Mrs. Claus. The birthday girl went with a tight red strapless dress with faux fur stitched to the top and the bottom. She completed the look with long red gloves, a black belt and a matching cloak.

Meanwhile, The Neighbourhood vocalist complemented his girlfriend in a Santa costume with a collared shirt underneath.

At one point in the night, the crowd sang “Happy Birthday” to Eilish as she blew out the candles on her candy cane-themed birthday cake with Doja Cat standing next to her.

Eilish – who typically keeps her love life out of the public eye – looked like she was loving all the PDA with Rutherford, who she previously called the “hottest f–king f–ker alive.”

The romance between the two was initially met with hesitation from fans over their 10-year age gap. Eilish and Rutherford clapped back at the haters when they made their relationship Instagram-official in matching Halloween costumes this year – with Eilish dressed as a baby, and Rutherford as an elderly man.

The “Lovely” songstress and the “Sweater Weather” singer first sparked romance rumors in October when they were photographed holding hands at Halloween Horror Nights at Universal Studios. They confirmed suspicions with a steamy makeout session a few days later and finally made their red carpet debut last month.
