We recognized musician Phil Collins' pretty daughter during the episode, and a quick check on the imdb website confirmed that it was in fact Lily playing party organiser Phoebe Abrams!
Check her out at 1:50 and 3:50 here:
She's set to star in next week's episode too -the final one in the first series of 90210 (no more Monday night 90210 action this summer then-sob!)
Lily at a charity event earlier this year
Did you see the Veronica's performing too?!
Will you miss 90210 when it finishes next week?! Let us know!
