[Updated 10 a.m. 3/12/15] Comedies “Mom,” “Mike & Molly” and “2 Broke Girls” have earned early pickups from CBS, although news of the Chuck Lorre sitcoms’ return leaked out via social media a day before the network was formally ready to make the announcement.

“Mom” will be heading into its third season, while “Mike & Molly” will be in its sixth season. “2 Broke Girls,” which is exec produced by Michael Patrick King and Michelle Nader, will be going into its fifth season.

“Mom” has growing critical buzz, and Allison Janney’s Emmy win last year for her work in season one likely sealed the deal. “Mike & Molly,” which stars Melissa McCarthy and Billy Gardell, has been a utility player for the Eye, although there are questions about how long McCarthy will stick with the show once her current deal expires as her film career continues to blossom.

Word of the early renewals for “Mom” and “Mike & Molly” surfaced Wednesday afternoon via social-media messages from staffers on the shows who were excited to share the good news.

“Mike & Molly” producer Julie Bean posted an Instagram photo of Lorre delivering the news to the production team, while “Mom” writer Sheldon Bull spread the word via Twitter. Both messages were quickly deleted, but by then, the horse was out of the barn.

CBS tends to announce its series renewals in large batches, so undoubtedly Eye execs were irked by the social-media leaks. The early news came on the same day that Jim Parsons, who appears on Lorre’s “The Big Bang Theory,” earned his star on Hollywood’s Walk of Fame, an event that brought CBS, WBTV and Lorre Prods. execs together. “Big Bang” is already renewed for another two seasons under a three-year deal reached between the network and studio this time last year.

CBS’ official confirmation of the three renewals does pose a question of whether “The Odd Couple,” the network’s freshman comedy starring Matthew Perry and Thomas Lennon, will return.
