Sir Elton John shows off his son for the first time

Sir Elton John has posed for his first publicphotograph with his newborn son.

The Rocket Man singer and his civil partner David Furnish welcomed a son called Zachary on Christmas via a surrogate mother.

After a month of being new dads, the couple has now posed for a family portrait for OK! magazine, showing off their tiny tot.

The 63-year-old also confirmed he was present at the birth, and couldn't believe how fast his child arrived into the world.

"He shot out like a rocket. There just aren't proper words to describe that feeling. It's indescribable. It was just, 'We have a son'," the Sun quoted him as telling OK! magazine.
