Thanks to TooFab for posting this, which totally made my day.

Aubrey Peeples will be playing the pink-haired leading lady.  Peeples is most well-known for her role as Layla Grant on Nashville, which shows the actress' singing chops! I cannot wait to hear her belt out the Jem theme song.
Stefanie Scott will take on the role of Kimber, Jem's annoying younger sister and keyboard player for the Holograms. Scott has starred in Disney Channel's A.N.T. Farm and, also released a number of singles while working for the network.

Another former Disney star,  Hayley Kiyoko, who will play Aja. Aja is on the drums and doesn't mess around on and off stage. Too Fab says, "Hayley previously starred in the Mouse House film Lemonade Mouth and currently appears on ABC Family's The Fosters. She also has performed with bands like Hede and The Sunners and released her own solo EP in 2013."

Aurora Perrineau, who was cast as Shana. Too fabs says "she appeared in the 2013 film A House Is Not a Home and is the daughter of Lost star Harold Perrineau."

Now if they can just tell me who will play The Misfits, Synergy and Rio!
