They got TRICKED, but these videos are your TREAT!

To celebrate Halloween, check out two of our fave country gals, Taylor Swift (above) and Kellie Pickler (below), get pranked by talk show host Ellen DeGeneres!

Whoa, that was quite a tumble, T-Swizzle! Hope there are no scars!

And tune in to Ellen this Tuesday to see the one, the only, Justin Bieber!

Did you play any Halloween tricks on your friends yet?! Tell us about them!
