DRIVING AWAY HER KIDS!

Heidi Klum’s new man is young, scrappy and hungry — for sex, sources squeal! It’s been more than six months since the supermodel, 45, introduced Tokio Hotel guitarist Tom Kaulitz, 29, as her boyfriend, but insiders tell Star the couple still can’t keep their hands off each other! “Heidi brags to everyone about how Tom has sex with her six times a day,” the tipster tattles, adding that though it “must be nice, it’s freaking out her kids!” While Heidi’s rep denies Star’s story, our source says the TMI tales of her sizzling behavior between the sheets have landed Heidi in hot water with her mortified teens, Helene, 14, and Henry, 13! “Helene thinks her mom should show more discretion, and Henry is really embarrassed that kids make fun of him for having such a showy mom.”
