From Madison: “Last week I was working on a new project, guest-starring on a new Disney XD show...”

Madison Pettis made a guest appearance on the Disney XD new series, "Lab Rats." Yesterday (January 24), Miss Madison posted these photos above of her time there. Nice pic of Madison and Billy Unger! It looks like Madison's character name is Janelle for the episode.

The wait is almost over, "Lab Rats" is set to premiere on February 27th!!!

Also, more good news from Madison as she tweeted this about her show, "Life With Boys":

"And for my US fans--YES--"Life With Boys" will be coming on here too! An announcement is coming soon!"

Sounds great!!!!
