Chloe Sevigny will embark on a new adventure in 2020: motherhood. The American Horror Story actress, also starring in the upcoming HBO miniseries We Are Who We Are, is about five months pregnant, expecting her first child with boyfriend Sinisa Mackovic, TMZ reports. The outlet spotted the couple out and about in New York City on Monday. Mackovic, director of the Karma Art Gallery, walked with his hand on Sevigny's baby bump, clearly visible beneath a tight-fitting dress. The couple have been dating for more than a year. In Touch Weekly rounds up more celebrities expecting babies in 2020. (Another well-known actress just became a first-time mom at 47.)
