Brad Pitt and Angelina Jolie have a brainiac in the family — their eight-year-old son Maddox!

Not only does the Cambodian-born cutie have the arguably the best-looking pair of parents on the Planet, the oldest member of the Jolie-Pitt 6 (Brangelina has three biological kids: Shiloh, 3, and Knox and Vivienne, 19 months; and two other adopted children, Pax, 6, and Zahara, 5.) also has the brains of a pint-sized Einstein.

“Maddox is beyond smart — he’s amazingly brilliant. Brad and Angie say his IQ is off the charts.”

Yep, now we feel completely inadequate!

Angelina adopted Maddox in 2002. Brad adopted him in 2005 after falling for Angie. Now the superstar couple can’t stop raving to pals about their Golden Boy, who they claim is intellectually-gifted and has a astronomical IQ, a tipster divulged in the March 15 issue of The National Enquirer.

After all, the jet-setting tot has been educated as some of the world’s most exclusive schools, including the prestigious Lycee Francais. Maddox takes piano lessons, is an avid soccer player, and speaks fluent English, Spanish, and Khmer — the language of his native Cambodia.

“Maddox loves books and tinkering with scientific gadgets. He whizzed through the Diary of a Wimpy Kid book series at a rate of one book per day, and he’s also a gifted painter and sketch artist.”
