‘Nashville’ Season 3 Spoilers: Alexa Vega Joins Cast As Single Mom

Season three of ABC's country music drama, "Nashville," will see a plethora of new faces. According to Deadline one of those new faces will be "Spy Kids" and "Machete Kills" actress Alexa Vega. She has been tapped for a three-episode arc as Kiley.

Vega's character is described as Gunner's (Sam Palladio) first love and high school sweetheart. She’s now a single mother who’s recently arrived in "Nashville" with the intention of providing some stability for her 10-year-old son that she had at a very young age. It has not been revealed if Gunner is the father but all signs point to yes.

It has also been revealed that Brette Taylor ("Return To Paradise," "Laws Of Attraction") has also booked a recurring role on "Nashville." Taylor's character is named Pam and described as Luke Wheeler’s (Will Chase) new back-up singer. Pam is an incredibly talented singer in her own right and quickly becomes Deacon’s (Charles Esten) muse, even more so when her complicated and dark past is revealed.

Furthermore it was revealed "Dancing with the Stars" pro Derek Hough will receive his own multi-episode arc for season three of "Nashville." Hough will play Noah West, a 20-something movie star who will cross paths with the Nashville characters when he's tapped for a leading role in the biopic of a famous country singer.

"Nashville" returns Sept. 24 on ABC.
