Teaming up with a big-name weight-loss company is so on-trend for stars that even A-listers are in on the game. Now, Janet Jackson is stepping up as the rep for Nutrisystem, a food delivery program.

“I’m not viewing this as a diet,” she tells USA Today. “I’m not putting a number on it. I don’t look at the scale. I’m going about it in a different way this time.”

The iconic pop singer’s weight has yo-yoed in the public eye for more than 20 years, and she says her obsession with maintaining a slim figure started in childhood. She said her late brother, Michael, also contributed to her body-image issues with his playful ribbing about her backside.

“He talked about my butt being too big. Some of us have a big butt, and some of us don’t. I’ve learned to accept it and love it.”
