Aubrey Plaza stepped out with partner Christopher Abbott on Broadway just days after her pregnancy was revealed. Plaza, 41, and Abbott, 40, jointly attended the afterparty following the opening night of his Broadway play Death of a Salesman on Thursday, April 9. The couple were all smiles at Katz's Deli in New York City. Abbott stars as Biff Loman in the Broadway revival of Arthur Miller's famous play, which is staged at the Winter Garden Theatre. The outing comes less than one week after Plaza's rep confirmed to People on Tuesday, April 7, that she and Abbott are expecting baby No. 1.
