The premiere episode of "Hot in Cleveland," TV Land's new sitcom starring Betty White and Valerie Bertinelli, kicked off with a blast Wednesday night.

The critically acclaimed show pulled in nearly 5 million viewers with its premiere episode -- making history as the highest rated and most watched telecast for the network ever, ET has learned.

Also starring Jane Leeves and Wendie Malick, the show follows three Los Angeles transplants (Bertinelli, Leeves, Malick) who take on a new lease on life together in Cleveland. Their new rented home comes with a very feisty and loveable caretaker, played by White.

"Hot in Cleveland" heats up the airwaves Wednesday nights at 10 p.m. on TV Land.
