Maddie Ziegler has become a bonafide success. The 13-year old dance prodigy got her big start on Lifetime's hit reality show 'Dance Moms', which is rumored to be leaving after the conclusion of Season 6. However, it was Maddie’s music video trilogy with recording artist Sia that skyrocketed her to mega fame. But stardom does come with its down side. Maddie Ziegler’s official Instagram was recently hacked. This is just a walk in the park compared to what stars can face from the ghastly and uncharitable amongst us. One of Maddie’s 'Dance Moms' co-stars, JoJo Siwa, was criminally harassed by a crazed man, Phoenix Sundown, who sent her severl pornographic packages. Luckily Sundown was arrested this past September. While in jail and awaiting trial he claimed to be able to talk to JoJo, Maddie and other members of the 'Dance Moms' cast in code via the internet. Sundown was recently sentenced to 3-years in prison.
