The 31-year-old recently opened up about her new fuller shape, insisting she loves her body no matter what critics say.
But she has not always been so confident and was pressured into shedding 15 pounds during the middle of her Stripped tour with pop star Justin Timberlake 10 years ago, reported Us magazine.
"During the promotion of my album Stripped, I got tired of being a skinny, white girl. The next time my label saw me, I was heavier, darker and full of piercings!.
"I had gained about 15 pounds during promotion and during my Stripped tour. They called this serious emergency meeting about how there was a lot of backlash about my weight," she said.
So they said that it would affect a lot of people if I gained weight - the production, musical directors.
"They claimed people I toured with (like Timberlake) would also miss out if I gained weight because I would sell no records or tickets for my shows. I was young, so I lost the weight quickly and was toothpick thin during Back to Basics promos and touring (in 2006)."
