Some pieces of Gossip Girl spinoff cast news have come to light in recent days.

The Hollywood Reporter is reporting that Andrew McCarthy will be joining the Gossip Girl spinoff as Lily's father, a music company exec. The show will follow the teenage years of Serena's mom Lily, played by Brittany Snow, in 1980s Los Angeles.

Meanwhile, EW reports that Lost alum Cynthia Watros is close to a deal to play Lily's mom, CeCe. Also  onboard is Ryan Hansen, best known as Veronica Mars' aptly named Dick.

He'll play Owen's (Shiloh Fernandez) pal, Shep, who's crushing (futilely) on Krysten Ritter's character, Carol (Lily's sister). Hansen is currently on Schwartz' web series, Rockville.
