Kelly Clarkson dropped 18 lbs in a month! So how did she do it?  Clarkson says in the February issue of Cosmopolitan that she "just cut back on my portions. I stopped eating late at night, and I work out a little more than I used to, and I literally dropped 18 pounds in a month. I think it happens when you get really busy. But when I'm on my off-time -- girl, those 18 might come back!"

Clarkson says that it helps to work out with her new fiancé Brandon Blackstock. "Brandon and I both have bikes on the back of the bus, and we both love the outdoors," she then adds that "once your lifestyle becomes more active, obviously you drop weight."
