Back when they were both Disney Channel stars, [Miley Cyrus](http://www.j-14.com/miley-cyrus-210 and Selena Gomez used to be pretty good friends, but in recent years the girls have had their rumored differences — and after what happened at Miley's concert in Milan, Italy, on Sunday, we're guessing the controversy between the stars is about to get stirred up all over again!
In the video below, Miley takes a cardboard cutout of Selena from someone in the crowd, serenades it, and then hurls it back into the audience. We're sure the gesture was completely innocent — but given the girls' complicated history, it's hard to know what the "Wrecking Ball" star was really thinking.
Do you think that Miley was trying to hurt Selena's feelings? Tell us in the comments!
