Ready for more of today’s TV dish? Well…

• CBS has picked up 3, a dating reality series set to debut this summer. Based on the Israeli format, the show follows three women in three different stages of life searching for love.

• Two Lost vets have booked guest spots in the same episode of USA Network’s upcoming drama Common Law. Per EW.com, Jeff Fahey (who played Lapidus) will appear as a “hard-drinking narcotics detective” who was a mentor of sorts to Michael Ealy’s character, while Kevin Tighe (who played John Locke’s dad) is a detective who helped jumpstart the career of Warren Kole’s cop.

• TBS has ordered 35 additional episodes of Tyler Perry’s latest comedy, Tyler Perry’s For Better or Worse, which premiered last November.

• Looks like Lip’s competition on Shameless isn’t going anywhere. Deadline reports that Zach McGowan, who plays Karen’s fiancé Jody, has been promoted to series regular, beginning with the Showtime series’ third season.

• Behind the Music returns to VH1 beginning Thursday, March 15 with the first of six new episodes. This season’s featured artists include Pitbull, Game, T-Pain, Akon, Brandy and Nas.

• VH1 is also developing a talk show for blonde bombshell Jenny McCarthy, aptly titled The Jenny McCarthy Show. The potential series — which sounds an awful lot like E!’s late-night gabfest Chelsea Lately — will feature McCarthy skewering anything and everything pop culture-related, conducting celeb interviews and leading guest panels.

• Discovery has renewed one of The Soup‘s favorite shows, Gold Rush, for a third season, per The Hollywood Reporter.

• HBO has purchased 44th Street, a Broadway-themed comedy from NewsRadio helmer Paul Simms, Deadline reports.
