Lily Collins is one proud daughter!

On Saturday, Phil Collins and his Genesis bandmates took over London's O2 Arena for their final concert ever to close out their The Last Domino? Tour.

The Emily in Paris star was in attendance, and shared an Instagram tribute to honor the her rockstar father's last performance with his Rock and Roll Hall of Fame-inducted band.

"Tonite [sic] marks the end of an era," Lily, 33, wrote in the post alongside a picture of herself sitting backstage, as well as with images and videos from the band's concert in England.

"To have witnessed this last show was truly the memory of a lifetime and an event I shall hold in my heart forever. Endlessly grateful doesn't begin to do it justice," she continued. "So much love was left on that O2 stage and an even bigger amount shared between an audience who didn't want it to end."

Lily concluded her sweet note by expressing her gratitude for the band, her dad, and her brother, Nic Collins.

During the concert, Phil, 71, entertained the crowd onstage while sitting in a chair due to health issues. His bandmates Mike Rutherford and Tony Banks joined him, while 20-year-old son Nic stepped in to play drums.

Speaking to the audience, Phil said, "Tonight is a very special night."

"Of course, we're playing in London. It's the last stop of our tour, and it's the last show for Genesis," he explained. "It's difficult for us to believe that you still came out to see it. I guess after tonight we've all got to get real jobs."

Genesis was founded at the Charterhouse boarding school in Surrey in 1967, and at one point included Peter Gabriel and Steve Hackett, among others. The band won one Grammy Award (out of five nominations) for best concept music video for "Land of Confusion" in 1988.
