'Dance Moms' Star Abby Lee Miller -- Goodbye, PA ... Hello, LA!!!

"Dance Moms" star Abby Lee Miller is bringing her east coast, in-your-face style to the west coast ... and setting up shop in L.A. ... and we're guessing some thirsty L.A. moms and their daughters will be standing in a long line.

According to our sources, Miller is opening up a branch of her dance studios in Santa Monica, which will be known as ALDC LA (Abby Lee Dance Company Los Angeles). Our sources say Miller is renting an apartment nearby.

We're told Miller is working in the same studio where "Dancing With The Stars" rehearses while she waits for her new space to be renovated.

Miller's L.A. victims will appear on her show. We're guessing there will be a fresh look of plastic ... among the moms.
