Just days after Demi Moore was rushed to the hospital for apparently doing what the kids call "whip-its" — inhaling nitrous oxide for a giggle-inducing high — The New York Post is reporting that the 49-year-old actress is calling out soon-to-be ex-hubby Ashton Kutcher on his teenage-like behavior.

Immediately following their split, Ashton, 33, spent the holidays in Italy with screenwriter Lorene Scafaria, and more recently, he was spotted partying it up with Brazilian supermodels during Sao Paulo fashion week.

“Now he’s carrying on like a teenager, goes around with other women, and then, when he’s feeling scared and lonely, he reaches out to Demi," a source told The New York Post.

"It’s really taking its toll on her. Demi is exhausted and humiliated."

"He goes between doing ridiculous things and then making overtures to Demi," the source continues. "She took her marriage very seriously, she gave it 100 percent, and his behavior is confusing to her."

Confusing? No, Demi. He's a man-child, and you're better than that. It's time to drop him like a bad habit … along with the whip-its!
