Obama's family: Three 'strong, tall women'

President Obama says his wife and two daughters can always keep him in line.

"I've got three opinionated, strong, tall women," Obama told People in an interview that hits the newsstands on Friday. "If they get together, they can have fun about my ears or being too loud, or how I dress."

People also reports that daughters Malia and Sasha have tutored the president on social media sites Vine and Instagram, and can be as embarrassed by their parents as any teenager:

"'Malia had friends over, and there was a question about whether she was going to even introduce them (to her dad), because sometimes he gets a little formal, asking them about school and interests,' the First Lady tells People. 'She says, 'I don't know if my friends can handle that.' Then she turns to her husband and says, "but she said that you actually did quite well.'"

"'I acquitted myself well,' notes the President. 'I did not embarrass her.'"
