Caitlin FitzGerald looked flirty and carefree in a captivating strapless dress at Showtime’s “Masters Of Sex” Season 2 Summer TCA Press Tour in Culver City yesterday (July 16), She’s been described as poignant in her role as Libby Masters.

Libby, the wife of real-life pioneering sex therapist William Masters, is a conflicted and complicated role.

She’s deeply troubled by her inability to have a child and husband’s lack interest in the bedroom. She struggles to reconcile her passionless marriage with her husband’s preoccupation with sex in his research.

Caitlin, 31, has won critical praise for playing the highly nuanced role.

She has plenty to draw on from her own privileged life, as an American Blueblood, which must have produced its own inner conflicts.

Her father, Des FitzGerald, is the former Chief Executive ContiGroup, a multi-national agra-business. Her paternal grandfather was deputy CIA director during the Kennedy administration.

Caitlin attended Concord Academy, a swank private school in Maine and graduated from New York University. She studied drama at the Stella Adler Studio of Acting and at the Royal Academy of Dramatic Art in London.

Showtime has renewed the show for a second season with a 12-episode arc.

Caitlin also has a role in the upcoming indie comedy film “Brother’s Keeper” directed by Ross Katz.
