Relationship status at 20: Britney and then-*NSYNC member Justin Timberlake broke up in 2002 after dating for nearly three years, and he went on to release "Cry Me a River" in November of that year, which is rumored to be about Britney cheating on him.
Quoted at 20: In October 2002, Britney opened up about fame in Rolling Stone, saying, "I feel changed. I'm a little more serious than I was. It's really weird, because you're a star, and everything is about you all the time — and I'm tired of that. I want to have a different perspective. And not have all my family and all the people I know working for me. I want to hang out with my friends and be a nobody. Because that's how you become reinspired."
