(Cover) - EN Showbiz - Elton John says that baby son Zachary is his little pride and joy.

The singer couldnt stop gushing about the little boy in a TV interview and revealed the lengths he and partner David Furnish go to for ensuring he grows up happy and healthy.

The couple, who became parents on Christmas day last year when a surrogate gave birth to their baby son, are absolutely smitten with their bundle of joy.

I love my little boy, hes my little pride and joy. Hes the most gorgeous little bubba in the world, Elton told talkshow host Barbara Walters.

The 64-year-old then revealed that he gets breast milk from Zacharys biological mother delivered to their home by courier.

Breast milk is believed to be more nutritious and beneficial to a babys development than artificial substitutes available on the market.

We have the breast milk FedExed from where she [Zacharys biological mother] is, the star admitted.

The rocket man singer, who has been with partner David Furnish for 17 years, recently revealed the inspiration behind the little boys full name, Zachary Jackson Levon Furnish-John.

Zachary is one of my favourite names, and Davids. And one of our favourite churches in Venice, where we have a home, [is] called San Zaccaria, he said. It was John the Baptists fathers name and John the Baptist was born three days before Jesus Christ.

Jackson is a name Ive always liked and Davids dad is called Jack and its an old English name that means son of Jack. And it was just going to be Zachary Jackson and then as he was born on Christmas Day, and [my] song Levon says he was born a pauper to a pawn on a Christmas Day, I chucked that in for a bit of rock star influence.
