Matt Lanter Cheers On Shenae Grimes for 90210

Matt Lanter gets his cheer on while filming scenes for 90210 on Wednesday afternoon (September 26) in Los Angeles.

The 29-year-old actor joined costars Shenae Grimes, Jessica Stroup, Jessica Lowndes and AnnaLynne McCord on set, who were dressed down for a game of flag football.

Denise Richards was also spotted on set, running over lines with AnnaLynne.

She’ll play Gwen, “a sexy West Beverly High School Alum turned wealthy socialite, and is the head of a very exclusive women’s club filled with powerful women. There is nothing Naomi (McCord) wouldn’t do to become a member of this club, until she realizes it’s really a grown up version of a Mean Girls clique from high school.”

90210 returns to the CW on October 8th. 10+ pics inside…
