Johnny Vaughan's partner gives birth to a baby boy

Johnny Vaughan\'s partner Vanessa Howard had given birth to a baby boy.

The 54-year-old star has taken to his Instagram account to announce the arrival of Milton Vaughan, posting a picture of himself alongside his son, and saying he\'s "too proud for words".

Johnny - who previously hosted \'The Big Breakfast\' on Channel 4 - captioned the image: "Welcome to the World Milton Vaughan. Too proud for words. Thanks to staff of Chelsea and Westminster for an immaculate delivery and @vanessah50 for being beautiful and awesome. Wow! Just a Wow. (sic)"

Johnny - who already has Tabitha, 20, and Rafferty, 17, with ex-wife Antonia Davies - had remained tight-lipped about Vanessa\'s pregnancy right up until the birth.

And some of his celebrity friends were also clearly caught off guard by the announcement.

Kelly Brook - who previously co-hosted \'The Big Breakfast\' alongside Johnny - replied: "Woww!!! (sic)"

Jeremy Clarkson was more blunt in his response to Johnny\'s initial post, suggesting he had no idea Vanessa was pregnant.

The \'Grand Tour\' host - who is known for being outspoken - simply said: "What?"

However, fellow presenter Jamie Theakston was more enthusiastic about Johnny\'s baby news.

The former \'Live & Kicking\' star said: "Mucho Congrats JV (sic)"

Johnny split from Antonia in 2013, and prior to meeting Vanessa, he was struggling to find love.

The presenter - who first met Vanessa, 37, through mutual friends - said a few years ago: "I\'m finding it very hard, to be honest. I\'ve struggled.

"I\'ve been on a few dates but I don\'t know what to say."
