David Tennant and his wife Georgia enjoyed a refreshing stroll with their fifth child Birdie in west London on Saturday.

Tyler revealed the name of his youngest sibling during an appearance on Lorraine, excitedly telling the host he wanted to give a shout-out to his family.

He said: ‘Hi mum, I love you mummy. Hi dad, Wilfred, Olive, Doris, Birdie… I love you all. Sorry, I’ve always wanted to do that,’ which led Lorraine to agree that he ‘had all the family covered.’

During the interview, Ty also spoke of the moment he met his adopted dad on the set of Doctor Who when he was just five years old.

The budding actor spoke of his close bond with the sci-fi superstar whom he calls his father, and why he would love to be the third Doctor in the family.

David met Ty’s mum Georgia when she had a guest role in the 2008 episode The Doctor’s Daughter – and it was then when Ty met his TV hero.

‘I watched him on TV as the hero, and it was crazy how much your life can change.’
