Lynn Herring's return to GH as Lucy kicks off Monday, and she's got some high-profile company: Meredith Vieira guests as an employee of Lucy's new company, CoeCoe Cosmetics.

I was so excited; I got to hug her and talk with her a bit. I said, ‘Meredith, please, please come back!’ And she said, ‘If they write it, I will come!’ "
