Inventor Tom announced the happy news on his Twitter account on Wednesday (5 June), writing: "I'm a DAD! Lovely baby boy arrived yesterday morning. Both mum and baby are well."
Tom didn't reveal what the new arrival's name is.
Among those who sent congratulations were The Apprentice's Lord Alan Sugar, who wrote a similar message: "Congratulations @inventor_tom, whose baby boy arrived yesterday morning. Both Mum & baby are well."
Tom retweeted one congratulatory message from a follower which read: "Your ultimate and best invention!"
He later tweeted: "Thank you for your kind Tweets. #ProudDad."
Tom won the seventh series of The Apprentice in 2011 and went on to launch his first invention, the Stylfile, which is a curved nail file.
Congrats to Tom and Sarah!
