Guess the song 3 with prize

Ok another one. The last ones winner was x_zinkaloohoo_x ( I hope I spelled it right) but any way congrats. Now you can tell by the title so I don't have to explain. Here are the rules
No looking up the song
No saying that the song is stupid
No bad language
Here we go
Oh and if it's from a show say the show and the name of the song ( had some complications with that)
Lyrics
Ya ya ya a ya ya ya a ya ya ya ya at first we thought babs was so really really sweet a new friend to have and it seemed like such a treat. But then we found the truth she's just a bully and a beast she went from bans ya to a bully and a beast
