Armstrong exits 'This Morning' for birth?

Alexander Armstrong was reportedly forced to leave This Morning yesterday when he found out his wife had gone into labour.

The comedian was due to appear on the show with his partner Ben Miller.

However, The Sun reports that he found out he was about to become a dad for the third time while he was in his dressing room.

Miller went ahead with his appearance and told hosts Phillip Schofield and Holly Willoughby: "It's really exciting - Hannah called Xander and he just sort of said, 'I should go now'... I think it's three weeks early, but so was their last one, he said."

Armstrong and his wife already have two sons, Rex and Patrick.
