Hollywood star Brad Pitt has spoken of his love for his three children, insisting his feelings for his biological and adopted kids are equal.

Pitt became a biological father for the first time last month when his girlfriend Angelina Jolie gave birth to Shiloh Nouvel in Namibia.

He also became the legal guardian to Jolie's adopted children Zahara and Maddox earlier this year.

Pitt gushes to Newsweek magazine, "Whether you have them or adopt them, they're all blood. And the funniest people I've ever met."

"It's absolutely sublime."

The Troy star accompanied Jolie when she picked up Zahara from an Ethiopian orphanage last year.

He says, "I look at Zahara and imagine what her life could have been."

"You want to grab as many of these kids in your arms as you can. They need our help, and we should be doing more."
