Actress Lily Rabe is dating her theatre co-star Hamish Linklater, according to a U.S. report.

The American Horror Story actress has grown close to Linklater during rehearsals for a new production of William Shakespeare's play Much Ado About Nothing, according to New York Post gossip column Page Six.

The pair recently moved in together, according to an article published in The New Yorker magazine which states Linklater has "upgraded to his girlfriend's place on the Lower East Side (in Manhattan), which is cat-free".

The upcoming production of Much Ado About Nothing is part of the free Shakespeare in the Park series, held at Central Park's Delacorte Theater. Performances will begin on 3 June (14).

The actors previously worked together in 2011 on a play called Seminar.
