Melbourne, Feb 7 : American actor Brad Pitt has revealed about his joy of becoming a father to not just one but six kids.

Pitt, who is the father of Maddox, Pax, Zahara, Shiloh and twins Vivienne and Knox, revealed that he is very proud to have them in his life and that none of his career achievements can compare to them.

"This is what I''ve wanted for a long time," the Daily Telegraph quoted him as saying.

"Being a father in a big loving family like I have is the high point of my life. It''s a very comforting feeling. There''s nothing better than being a father.

"It can be tiring sometimes, but I''m lucky that Angie is so incredibly organised and has so much energy. She''s amazing.

"The twins take a lot of her time and it''s very demanding looking after them, but she always makes sure that our other children get a lot of love and attention," he added. (ANI)
