Momsen parted ways with the show last year and is now pursuing a career as front woman of band Pretty Reckless, and Meester said that she can't get enough of her music.
'She's so talented, and anyone I know that's heard her music is a huge fan,' she told E! News. 'You can't help it. She's also an incredible actress and just a lovely girl.'
Although she's now trying her hand at music and has an album awaiting release, she admitted that she would never follow in Taylor's footsteps and quit acting for good.
'Both is where it's at,' she said. 'If I had to choose, I think I'd be very unhappy.'
