Janet Jackson sat down with ABC’s “Good Morning America” for an interview that aired Thursday (Dec 15) where the 45-year-old entertainer announced that she is the new face and body of the popular Nutrisystem diet program.

Janet says her self and body image issues, which started when her brother (late Pop idol Michael Jackson) teased her about her weight when they were kids, inspired her to inspire others and become the face of Nutrisystem.

“It’s a matter of learning how to keep it off, that maintenance and they have a program for that,” Janet shared. “My success plan is to be healthy and feel good about me.”

In addition to the Nutrisystem announcement, Ms. Jackson also talked about her niece Paris Jackson, and what she thinks about her signing on for a role in the upcoming movie “Lundon’s Bridge and the Three Keys.”

“I’m happy for her because this is what she wants to do,” she said. “[But] I said, ‘You should really take this time to enjoy your youth to its fullest’ because you lose so much of your childhood in this industry.”

Jackson also discussed how she’s doing after he trial of Dr. Conrad Murray, the doctor who was found guilty of involuntary manslaughter in the death of her brother, Michael.

“It’s been a great deal of happiness and a great deal of sadness,” she said.
