'Dancing With The Stars': Kellie Pickler, Aly Raisman And More Rumored Cast

"Dancing With the Stars" hasn't officially announced the Season 16 cast, but the rumors are flying. According to TMZ, Kellie Pickler will be the first former "American Idol" contestant to join the cast of "Dancing With the Stars."

Other reported Season 16 contestants are "Bachelor" star Sean Lowe, Wynonna Judd and Olympic champ Aly Raisman. Boxer Victor Ortiz is also rumored. June Shannon -- Mama June from "Here Comes Honey Boo Boo" -- was an early rumor, but the reality star's involvement was shot down by TLC.

Casting rumors aren't just reserved for the celebrity contestants. Maks Chmerkovskiy is rumored to to be off the show as a pro dancer -- at least for this season.

The cast will be announced on ABC's "Good Morning America" on Tuesday, Feb. 26.
