Madonna reveals herself in 'Today' interview

Madonna has never been short for words. And the pop icon didn't disappoint during an interview with "Today" on Wednesday (April 18).

Here's a bit of what the Material Girl had to say about her life, family and music:

On the difficulty of her lifestyle: "To be a single mother of four and to work as much as I do, [I] live my life in kind of a metaphorical fishbowl. It's pretty challenging. But so far I've survived with sanity and humor in tact."

On what version of Madonna she's like at home: "To my children, there's mostly the one that comes home and says, 'Have you done your homework?' and 'Why are you wearing that?' and 'Why did you say that?'"

On disciplining her children: "Honestly I don't think I'm as tough as I should be. I think I need to be maybe tougher. It's hard though. It's hard. Every day is a negotiation."

On a recent photo in which her daughter Lourdes was caught smoking: "I don't approve of anyone smoking cigarettes, most of all my daughter."

On her musical future: "I have stuff left to say...I still feel like expressing myself that way."
