Ainsley did not make clear which one of his children, who keep their lives private, had welcomed their first child.

Fans and celebrity pals congratulated the chef in the comment section, with DJ and presenter Melvin Odoom said: 'Congratulations big man.'

Great British Bake Off winner Giuseppe Dell'Anno said: 'Congratulations. The photo is super sweet. Your heart must be bursting with joy.'

Radio presenter Anita Rani said: 'Ah best Grandad. Congratulations. What a great Christmas pressie.'

Harriott added: 'Thank you all for your lovely comments. Big love and hugs.'

Ainsley and his ex wife Claire split in 2012, but eight years later,  Ainsley told the Mirror that he still has 'love and feelings' for his wife.

He added that he now had a new partner and was 'enjoying having love and getting to share my life with someone'.

It comes after Ainsley attended Legends of Football Supported by Barclays in London in October.

The professional chef showed off some questionable dance moves while mingling with guests at the Grosvenor House gala - an annual event that celebrates some of the beautiful game's biggest names while raising money for music therapy charity Nordoff and Robbins.

He was on his feet and cutting some dubious shapes as the auction got underway - much to the amusement of those in attendance.

Other guests on the night included Football Focus host Alex Scott, DJ Pete Tong, Arsenal legend Ian Wright and Chelsea women's team manager Emma Hayes.

Hayes - who was attending the event following the death of her father - and Wright were honoured for their contributions to football prior to the fundraising auction.
