[artist id="1245169"]Jessica Simpson[/artist] hit the road last year to film her new VH1 show, "The Price of Beauty." At the time, the pop star had been inundated with negative press about her appearance and reported weight gain. And after an eye-opening journey around the world, Simpson said she learned what was truly beautiful about herself.

"I think that [the show] is such a great concept and I think it's going to be such an incredible show for women of all ages to watch. You definitely learn a lot about all these different cultures," she told MTV News about her show, premiering Monday (March 15) on VH1, adding that the filming was very personal for her.

"The reason why I wanted to go on this journey was to discover that, for myself, what was beautiful inside me and just to listen to these women talk and hear their stories," she explained. "And I had gone through a really hard time in the past year with people, just, they keep harping and me gaining weight, it made me so insecure that I really actually forgot who I was and I wanted to go on this journey to find myself again."

Now that she's back in the States, she said she can easily face any criticism or even be able to handle any line of questioning, even if it's about [article id="1633921"]touchy subjects like John Mayer[/article]. "I definitely learned that I allow too many judgments of other people to seep in," she said. "Even when you think you kind of got it together and you think you can ignore it, you do still fall asleep with those voices in your head. There's no way to stop that. I think that going on this trip, all these places, I really just found an inner peace. I found something within myself that I didn't know was there."
