Blake Lively has reportedly given birth to her third child with Ryan Reynolds

The notoriously private couple have welcomed their third child together.

Blake Lively has reportedly given birth to her third child with Ryan Reynolds, according to a report in Us Weekly.

Although the couple haven't yet announced the birth, a report by E! News claims that the child was born some two months ago and that the child's birth was kept out of the public eye since then.

Lively's pregnancy was only confirmed when she appeared on the red carpet of 'Pokemon Detective Pikachu' with a visible pregnancy bump in May of this year. Lively gave birth to two girls, Inez and James, four years ago and three years ago respectively.

Reynolds and Lively married in 2012, having met on the set of 'Green Lantern', Reynolds' regularly lampooned comic-book blockbuster. The couple were recently in Ireland, where Lively filmed 'The Rhythm Section', an espionage thriller directed by Reed Morano.

So far, neither Reynolds nor Lively have publicly commented on the news.
