Selena Gomez is reportedly uspet that Miley Cyrus dissed her during a concert in Milan, Italy, on 8 June.

The 21-year-old Hannah Montana star grabbed a cardboard cut-out of Gomez from a member of the audience while singing the song FU and then threw the cut-out back into the crowd.

Cyrus recited the lyrics to the hit song: "I got two, ooh, ooh letters for you, One of them's F and the other one's U, Cause what you gotta do, is go get yourself a clue, Only two, ooh ooh letters to choose, One of them's F and the other one's U, SMH, I'm pressing send on you'."

The 21-year-old Wizards Of Waverly Place actress was shocked by the act.

"Selena already knows that Miley will do anything for attention even if it means dissing other people," a source told Hollywood Life. "Selena would never do what Miley did and doesn't really have any respect for her in the first place. She thinks Miley's number one priority in life is getting attention and she actually feels sorry for her!"

"They have been catty and fueding since the Disney days and this is just a continuance of it. There is definitely no love lost and they talk sh*t about each other behind closed doors all the time. This just happened to be made public. Selena thinks Miley is lame, but expected this from Miley since they both don't like each other," the insider added.

However, this is not the first time that Cyrus has attacked Gomez. In 2008, the Wrecking Ball singer mocked Gomez in a YouTube parody.
