VIDEO: Swift Justice for Miley Cyrus

Miley Cyrus should pick her video battles carefully.

A couple of months ago, the Hannah Montana star took a few catty swipes at fellow Disney star Selena Gomez in a YouTube spoof.

Now, Selena’s buddy, Taylor Swift—who’s dating Joe Jonas, brother of Miley’s ex and Selena’s current beau, Nick Jonas—has fired back on behalf of her buddy.

Swift has just released the video for her song “Love Story,” and the romantic clip features the songbird playing out a Romeo and Juliet scenario with none other than Cyrus’ underwear-modeling boyfriend, Justin Gaston.

Check out selections from the video below:

Whoa! Talk about taking things up a notch. This has the potential to get really ugly—though perhaps not as ugly as some video exchanges.
