Taye Diggs' son stars in Got Milk? advert with dad

Taye Diggs and Idina Menzel's son has made his modeling debut alongside his actor dad in a new Got Milk? advert.

The Private Practise hunk stars with Walker in the organisation's latest campaign with Kellogg's, which aims to provide more than one million breakfasts to kids in need, and Diggs insists it was a very special moment sharing the spotlight with his three year old.

He tells People.com, "Being able to shoot the Got Milk? ad with my son was one of the better times in life just because, obviously, the ad is going to last forever."

The father-son duo are featured sharing a bowl of cereal and flashing bright white smiles with milk moustaches, but the 42 year old admits he had a tough time getting the tot to focus on the shoot.

He adds, "We had to constantly make up games and excuses just to keep him occupied. So when it seems like he's smiling, he's actually roaring because he wanted to be a tiger."
