Betty White is on 'The Client List' for the season finale

Jennifer Love Hewitt's new racy Lifetime drama "The Client List" is welcoming a Hollywood A-lister for its season finale - the irascible 90-year-old Betty White, reports People.

In the season finale, Riley (Hewitt) is left in charge of The Rub, the day spa in Texas where she works, while her boss is out of town. White is playing Ruth Gibbons, the wife of one of Riley's clients. She offers Riley some advice about making a marriage last. Could it be that sending her husband to The Rub is one of her secrets?

The episode will also be directed by Hewitt. It will air Sunday, June 10 at 10 p.m. ET/PT on Lifetime.
