EAST HAMPTON - A legendary sitcom star is taking center stage in the Hamptons this summer.

Four-time Emmy-winner Marlo Thomas is starring in 'Clever Little Lies' at Guild Hall in East Hampton. News 12 caught up with 'That Girl' on stage before the night of her Hamptons stage debut.

"It's about a family, and like all families, it tells little white lies," Thomas said of the plot. "By the end of the play, you're not sure who's lying and who's telling the truth, and that makes it exciting!"

Thomas will be performing six nights a week, but she also plans to enjoy some quality Hamptons downtime with her husband, Phil Donahue.

'Clever Little Lies' runs through Aug. 3.
