Rinna, 48, will reprise her role as Billie Reed beginning March 8. Few details are known about her arc, but she will share "explosive" scenes with on-screen mother Kate (Lauren Koslow) and her character's former beau, Bo, played by Peter Reckell, network officials tell the trade magazine.
"I am so thrilled to be back and excited to be acting again," Rinna told THR. "I have done reality shows, talk shows and I thought, what a great way to come back and play a character that I love to play so much. Feels very full circle — like a new old chapter."
Since starring on Days of Our Lives from 1992 to 1995 (and returning from 2002 to 2003), Rinna has starred on Melrose Place and in the 2010 reality show, Harry Loves Lisa, with real-life hubby Harry Hamlin. She also competed in the second season of Dancing with the Stars and Season 4 of Celebrity Apprentice.
