Aly Michalka (18) and her 16-year-old sister Aj, are already a stone's throw away from superstardom. The workacoholic American girls act, model ? and sing.
The mega-talented duo shifted nearly one million copies of their debut album Into The Rush. With stunning follow-up Insomniatic, they'll hit the big time. The record contains 12 of the most sparkling pop tunes you'll hear on one album all year. Now that Britney's promising career is on the slide, the world is the Michalka siblings' oyster.
Best are Potential Break Up Song and Bullseye.
