Cleveland Cavaliers' guard Kyrie Irving, the first overall pick in the 2011 NBA Draft, has gotten his NBA career off to a rocky start.

According to recent reports, the former Duke guard has filed a police report in West Orange, N.J. against a woman he claims has been threatening him through Twitter, and making disparaging remarks on YouTube.

Irving has said that Jackson threatened to stab him. Irving's attorney filed a harassment complaint against Jackson, and a judge has issued a restraining order against her.

Jackson allegedly broke the restraining order by contacting Irving again.

Irving claims he only had one meeting with Jessica Jackson, who uses the Twitter name RealMissHawaii, and it was at a hotel lobby during the NCAA Tournament.

Jackson has posted videos on YouTube, where she speaks in a disparaging and threatening tone about Irving. She also claims to have a video of Irving masturbating on Skype. 

In the YouTube video, Jackson comments on Irving's supposed comments that Jackson is a man. Jackson then directs multiple derogatory and profane remarks at Irving in a video lasting 13 minutes and 25 seconds.
