Dustin Lance Black wants "a football team" of children

Asked if they're thinking about more kids, he said: "I'm already on baby number 12! Baby two is already raised and in college in my mind..."

Tom said: "He wants a football team - with a reserve."

And Lance added: "Or a family band! Like the Brady Bunch."

But the 24-year-old diver isn't thinking so far ahead.

He said: "Before you become parents, you do think about the future and how many you'd want to have. But now we have a nine-week-old baby, it's like, 'Let's see how it goes with Robbie...' "

The couple have decided against hiring a nanny but admit it's much easier for the 'Milk' writer to fit his work schedule around their son than it is for Tom.

Tom said: "Luckily Lance is a filmmaker - my office isn't as portable as his.

"I don't have a diving pool in the garden, so Lance often has Robbie sitting next to him while he works at home.

"I'm back in training now - I'll be up at 6am, probably feed Robbie, go train, then come back at 4.30pm and take that shift while Lance carries on working."

And Lance is glad to have the baby by his side while he's working.

He told heat radio: "I'm really lucky, I'm mostly just sitting at my laptop and Robbie is great as a writing partner.

"He doesn't give me any criticism."
