The 36-year-old singer admitted that both breaks came before the couple welcomedtheir daughter Willow in June 2011. However, she thinks they're "due" for another.

What is the major cause of tension between the pair? Hart's inability to stay awake before the two can have some alone time.

"He always falls to sleep putting Willow to bed," Pink explained. "The other night I said, 'Are you going to stay up tonight?' And he said, 'I would like to.' I said, 'I don't really know what that means. Should I light candles and open wine and put on a show like are we going big here. Or are you going to fall asleep again?'"

Turns out, Hart fell asleep again, putting the kibosh on Pink's romantic evening.
