Popsugar Celebrity Aly & Aj Aly and AJ Through the Years Pictures After All This Time, I'm Still Jealous of Aly & AJ's Cute Sisterly Bond 5 April 2019 by Kelsie Gibson Image Source: Getty / Tommaso Boddi Aly & AJ are back with new music, and my Disney Channel heart has never been happier. The sisters — Alyson Michalka, 30, and AJ Michalka, 27 — first rose to fame with pop hits like "Rush" and "Potential Breakup Song" in the early 2000s, but have since reinvented themselves with their '80s-inspired album, Ten Years. While their music has certainly evolved over the years, one thing that has remained is their sisterly bond. Whether their showing off their sweet harmonies on stage or they're hugging it out on the red carpet, it's clear that Aly & AJ are more than sisters —q they're best friends.
