The singer, who will turn 21 on Sunday, marked her special day surrounded by loved ones and fans during a sold-out performance at The Forum in Inglewood, California, on Friday night.

Accompanied by her family and boyfriend Jesse Rutherford, Eilish received a surprise birthday cake during her final “Hometown Encore” show before turning 21. With fans singing along, she blew out the candles to applause, expressing gratitude with a hug for her family.

After her family left the stage, Eilish humorously addressed the audience, saying, “Want to take shots? Give me two days. I am 21 in two days, it’s unbelievable.”

During the show, Eilish was joined on stage by Donald Glover (Childish Gambino) and Khalid. Glover took the spotlight for a rendition of his 2016 Һit “Redbone” and asked the crowd to wish Eilish a happy birthday. The performance also featured a duet with Khalid on their collaboration “Lovely” and Khalid’s solo Һit “Location.”

In a festive twist, Eilish performed “Have Yourself A Merry Little Christmas,” embracing the holiday spirit. Earlier in the week, she surprised fans with guest appearances by Dave Grohl and Phoebe Bridgers during her Thursday show, where she covered Foo Fighters’ “My Hero” with Grohl and performed a duet of Bridgers’ “Motion Sickness.”

Eilish’s new boyfriend, Jesse Rutherford, also appeared on stage with her, marking a public appearance following their red carpet debut at the LACMA Art + Film Gala in November. In a recent Vanity Fair interview, Eilish expressed excitement and happiness about her relationship with Rutherford, describing him as the “hottest person alive” and playfully acknowledging her accomplishment in attracting him.
