America wants more Lennon and Maisy, and ABC and the producers of 'Nashville' are delivering!

The Stella sisters have been upped to series regulars for Season 2 this fall after making only occasional appearances during Season 1. Chris Carmack, who plays Will, the gay country singer, also got a promotion after his plotline thickened during the end of the first season.

The Stellas play Maddie and Daphne Conrad, the daughters of Rayna James. During the Season 1 finale, fans -- and Deacon Claybourne (Charles Esten) -- found out that Maddie (Lennon) is Deacon's daughter, not Teddy's (Eric Close).

Aside from the daddy drama, the sisters regularly provided moments to stay tuned in to in Season 1, as well as some of the best musical numbers, including covers of the Lumineers' 'Ho Hey' and Hayden Panettiere's 'Telescope.'

The other big between-season change for 'Nashville' is producer T. Bone Burnett exiting to give way to Buddy Miller. Panettiere says fans should not be worried about this change.
