2. AJ Michalka (June 2006)
Joe Jonas’ second pretty blonde Amanda, Amanda Joy Michalka (or A.J.) was part of another Disney channel sibling pop group–Aly & A.J, now 78violet.
Allegedly the two broke up because their long distance relationship was too hard to maintain, although, really, we’ll never know the exact truth unless we hear it from the mouth of a Jonas.
