The expectant mom will drop by the NBC show on March 13 to reward a Biggest Loser challenge winner with a visit to her personal showroom. According to NBC, the winner will also be allowed to bring a fellow contestant to pick out anything from Simpson's clothing, handbag and skincare lines.
"I was so happy when I was asked to help style two contestants from The Biggest Loser," Simpson tells PEOPLE. "I am truly inspired by how hard these contestants worked to accomplish their goals for a healthy lifestyle."
Continues Simpson: "It was so much fun seeing the [contestants] try on clothes they would have never fit into before and feeling sexy. We had an amazing day together!"
And that's not it for Simpson.
Her new competition show, Fashion Star, in which she will judge aspiring clothing designers alongside Nicole Richie and John Varvatos, will premiere immediately after her stint that night on The Biggest Loser.
