Inglewood, California - Billie Eilish brought the house down at the Kia Forum last night with help from some extra special musical guests.

The singer is playing three shows at the venue as part of her Happier Than Ever tour, with the LA stops being dubbed "The Hometown Encore," as Eilish is notably from the area.

To make things extra special, the 20-year-old brought out some impressive talent to join her on stage.

Foo Fighters frontman Dave Grohl performed an acoustic cover of the band's song My Hero with Eilish. The performance served as a tribute to Taylor Hawkins, the band's drummer, who passed away in March.

Eilish also honored the late musician at the 2022 Grammy Awards while singing Happier Than Ever during the show. She donned a T-shirt featuring a photo of Hawkins during the performance.

After Grohl's surprise performance, the crowd erupted in cheers as the Bad Guy artist announced another special guest: singer Phoebe Bridgers. The duo performed Bridgers' hit Motion Sickness together.

Though they haven't yet formally collaborated, Bridgers covered Eilish's When the Party's Over on SiriusXM earlier this year. Bridgers will also be making special guest appearances on another major tour next year at several stops of Taylor Swift's The Eras Tour.

Eilish concludes her three-night stint in at the Forum with one final show on Friday night.
