The premiere of the ABC Family sitcom "Melissa and Joey" on Tuesday was the network's biggest series launch ever.

"Melissa and Joey" stars "Blossom's" Joey Lawrence as a male nanny who helps a woman, played by "Sabrina The Teenage Witch" star Melissa Joan Hart, raise her orphaned niece and nephew.

The show is something of a reunion for the pair, who also teamed up for ABC Family's 2009 TV movie "My Fake Fiance." 

Approximately 1.26 million viewers in the key adults 18-49 demographic tuned in for the premiere of "Melissa and Joey."
