The 19-year-old 'Never Say Never' hitmaker has asked his friends not to bad mouth Gomez even though she has made some cruel jokes about him since their break-up, reported Showbizspy.
"Justin has been saying that when he decides to get Selena back, he will. She's been bashing him but Justin has ordered everyone around him not to fight back.
"He told his friends and everyone else about Selena, 'she's off limits'. He told everyone to leave her alone. 'I don't want anyone saying anything negative about her,' is what he told his pals," a source said.
