Lisa Rinna brought Billie back to DAYS OF OUR LIVES back in March, but it looks like her visit is about to come to an end. "It was my last day on DAYS OF OUR LIVES," the actress tweeted yesterday. "Tomorrow I start a new gig. Off we go!" She hasn't yet posted anything about what her next job is going to be another acting role or perhaps another talk show but one thing's for sure: She's going to miss her DAYS co-stars! "Oh God," Rinna also tweeted, "it's so hard to say good-bye."
