Clementine Ford

Clementine Ford, the eldest child of Cybill Shepherd and a recent cast member of The L Word (where she played Molly), is joining The Young and the Restless in the contract role of Mackenzie "Mac" Browning, TVGuide.com has learned exclusively. 

Although Mac returns to Genoa City on Wednesday, April 1, her presence will be no joke to ex-husband Billy. The young lovebirds were married for the blink of an eye several years ago, until they discovered they were, you know, cousins. At that instant, they had their union annulled.

Y&R viewers, however, have since learned that the two might not have blood between them. Regardless, Mac will resurface at a most inconvenient time for Billy.

Mac previously has been played by Ashley Bashioum, Kelly Kruger and, most recently, Rachel Kimsey.
