Marsha on General Hospital
She made her first "appearance", so to speak, on 11/17, as a voice leaving a message on (presumably) James Franco's character's answering machine, in which she identifies herself as his agent.
Nothing on 11/18 or 11/19.
The promo video with Franco, shaving and then kissing him, where she's VERY HOT and seductive comes from the 11/20 show. Video still at these URLs as of 12/10 (second video):

If you want to download it, there's at least one version on YouTube.
Up through the 11/23 she hasn't appeared again.
