EXCLUSIVE UPDATED: ABC Family is banking on Melissa & Joey. Ahead of the series’ Season 3 premiere tomorrow, I’ve learned that the network has given the comedy starring Melissa Joan Hart and Joey Lawrence a back order for 20 more episodes. Additionally, ABC Family has ordered a 20-episode fourth season, making Melissa & Joey the network’s first comedy to reach 100 episodes. The additional Season 3 episodes will air in 2014. “One hundred episodes is a great accomplishment for any series and we are thrilled to give Melissa And Joey the opportunity to achieve this milestone, as they’ve delivered hundreds and hundreds of laughs over the seasons,” said Kate Juergens, EVP Programming and Development and Chief Creative Officer, ABC Family.

Melissa & Joey follows local politician and former wild child Mel Burke (Hart) who employs down on his luck “manny” Joe Longo (Lawrence), as she raises her teenaged niece (Taylor Spreitler) and nephew (Nick Robinson). Guest stars for the upcoming third season include Sterling Knight, Shannon Elizabeth, Trevor Donovan, Marla Sokoloff, Marissa Jaret Winokur, Jaime Pressley, and Doris Roberts, who will be appearing in two episodes as Joe’s grandmother. Executive producing the series are Bob Young & David Kendall, Paula Hart, Melissa Joan Hart and Joey Lawrence. Melissa & Joey posted ABC Family’s highest comedy debut ever in total viewers. Boosted by new companion Baby Daddy, the comedy’s second season eclipsed Season 1 in several key demos, such as Adults 18-49, Women 18-34, and Viewers 12-34.
