Troubled singer Justin Bieber was infuriated that his ex-girlfriend and singer Selena Gomez refused to answer his calls.
"Justin is spiralling out of control because he doesn't know how to deal with his emotions. He is enraged that Selena is not answering his calls and is totally avoiding him," Showbizspy.com quoted a source as saying.
"He is used to having whatever he wants and is beyond frustrated that he's not getting his way.
"He's taking it out on innocent people including Yovanna (model), whom he has completely dumped, because he got mad at her because she couldn't change her plans at the last minute to see him," added the source.
