It's official, Brad Pitt is off the market! RadarOnline.com has just learned the hunky actor is dating rockstar MIT professor Neri Oxman — and it's getting serious!

"Brad is absolutely smitten by her," an insider told the magazine. "Their chemistry is off the charts."

The actor — and father of six — has reportedly been flying to the East Coast to visit his new lady, and has spent much time at her luxurious Cambridge apartment.

"Brad has been spotted going into her apartment building on multiple occasions late at night and emerging the next morning after she leaves to teach," claimed the insider, adding that the Hollywood hunk even has a key to her pad!

Since Oxman doesn't cook — just like Pitt's ex, Angelina Jolie — he has been making romantic meals for them. They've also been ordering form her favorite restaurants and staying in to spend time together.

While Pitt's divorce and custody battle with Jolie, 42, is yet to be finalized, sources have claimed he and Oxman are moving fast in their blooming relationship.

"Brad and Neri have traveled together internationally," the Pitt insider told Us Weekly. They were reportedly spotted together at South Africa's Design Indaba conference just this February!

As RadarOnline.com reported, Pitt's pals previously told reporters that his bond with Oxman was purely "professional," though now it seems their romance is too hot to hide!
