Even more TV legends are coming together on season 2 of 'Hot in Cleveland.'

The TV Land sitcom is hosting a 'Mary Tyler Moore Show' reunion and pairing Moore with her former costar Betty White once again. According to Deadline Hollywood, Moore will appear in the Jan. 19 season 2 premiere of 'Hot in Cleveland.'

Details on her character are scarce, but Deadline reports Moore's character may have something to do with the storyline that saw White's character, Elka, get arrested at the end of season 1.

Entering into its fourth season (and second since the NBC/DirecTV deal), Friday Night Lights is a show in transition on numerous levels. The high school football drama returns tonight to DirecTV's 101 Network at 9 p.m. ET (NBC won't air this season until next summer) and for fans of the show, it's an episode they've long been waiting for.

Ever since the season three finale, as Coach Eric Taylor (Kyle Chandler) and his wife Tami (Connie Britton) stepped on to the East Dillon Lions decrepit football field, Eric's new home, the tension has been at an all time high in Dillon, Texas. How can Coach Taylor, a man whom many consider to be a high school football wunderkind, start from scratch with a team that doesn't even exist yet?

Brett Cullen has been replaced in the new CW series Life is Wild. This really comes as very little shock since I can't think of anyone who was looking forward to this series.

Cullen is being replaced by D.W. Moffett who was most recently seen on the summer series Hidden Palms. You may also remember Moffett from such forgettable series as Skin & For Your Love.

Personally, I think Moffett is a little young to play a seasoned veterinarian and father of a teenager, but I'm sure his youth had a lot to do with the recast.
