Welcome back, Tonya Lee Williams and Michael Damien.

The two former stars on The Young and the Restless are reprising their roles on daytime's number-one rated drama.

Look for Williams as Dr. Olivia Barber Winters on tomorrow's episode. There's no word yet on how long the Daytime Emmy-nominated actress will remain on the show.

Meanwhile, Damien - who also enjoyed a brief return to Genoa City as Danny Romalotti earlier this year - began taping scenes earlier this week.

His scenes will air some time in November. We'll let you know when.
