Lily Collins is proud to honor her father Phil Collins as he says goodbye to performing with his band, Genesis.

On Instagram, the Emily in Paris star, 33, shared behind-the-scenes footage from the band’s London performance on Saturday evening.

“Tonite marks the end of an era. 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. 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,” said Collins, who was pictured sitting on a piece of the band’s equipment backstage.

Collins continued, explaining how proud she is of both her father, whom she called an “inspiration,” and her brother Nic, who performs with the band.

“Thank you [Genesis] for the memories, thank you Dad for being such an inspiration and thank you [Nic] for making me the proudest sister there is. 50 years of songs later and still generations more to celebrate you long after this tour has finished,” the Windfall star wrote.
