AceShowbiz - Actress Beanie Feldstein had to keep her emotions in check while shooting "Booksmart" scenes with her acting hero Lisa Kudrow, so she didn't blurt out something stupid.
Jonah Hill's sister didn't realise she'd be sharing scenes with the former "Friends" star when she signed on for Olivia Wilde's directorial debut, and really had to keep her inner voice silent on set when she was around.
"I'm the number one Lisa Kudrow fan on this earth," Beanie tells WENN. "I have a sticker of her on my computer. She was literally one of the biggest things to ever happen to me."
"I find her to be the loveliest human being ever to exist. She is remarkable to watch. I'm such a fan that it was hard for me to function as a human being."
"In one scene, I was lying on the bed, and the first thing that came to my mind, as I was fake strumming the autoharp, was one of (Kudrow's 'Friends' character) Phoebe's songs on 'Friends': 'Monica, Monica, have a Happy Hanukkah'. In my head, I was singing this, and I kept telling myself, 'Beanie, if you sing that out loud, I swear to God... Keep it together, Feldstein. Mother of God, do not mess this up!' "
