Roscommon actor Chris O'Dowd and television presenter Dawn O'Porter are celebrating the birth of their second child, a baby boy named Valentine O'Porter, who was born nearly two weeks ago.

The pair already have a son called Art

The high-profile Boyle actor, who opts to keep his family life out of the spotlight, announced the news on Wednesday night on Twitter and cheekily joked about the price of nappies.

Dawn O'Porter tweeted that Valentine was born July 1.

O'Dowd's latest TV series Get Shorty will premiere on US cable network EPIX on Sunday August 13

O'Dowd also has a number of movies in the works including Vincent Van Gogh biopic Loving Vincent and the sci-fi thriller Cloverfield Movie

Also on the way for the busy actor is Molly's Game, the directorial debut of The West Wing creator Aaron Sorkin. It stars Jessica Chastain and is based on the true story of a former skier whose underground poker games attract the interest of the FBI.
