Michael J. Fox is begging former Spin City co-star Heather Locklear to join his ratings-challenged new sitcom, Breaking Celebrity News has been told.

"Michael has reached out to Heather about coming on The Michael J. Fox Show," a production insider revealed.  "He's totally driven to make the show a success and is willing to monkey with the format to do it.

"He thinks a well-received guest-starring visit by Heather might lead to a more regular role."

And Fox, 52, has a long memory, knowing that Locklear, also 52, added spice to his Spin City series nearly 15 years ago.

The actress has been credited for her show-saving abilities for years, as she not only raised the ratings on Spin City but also Melrose Place and Dynasty.

The Michael J. Fox Show, in which the actor's real life Parkinson's disease  is incorporated into the plot, has received dismal ratings on NBC, being bested by CBS' The Crazy Ones, starring another famous funnyman, Robin Williams.
