Mary J. Blige is being sued for allegedly bailing on a concert in Dallas last December -- and according to the lawsuit, it's kinda Mick Jagger's fault. TMZ has learned  a promotional company called Vision Entertainment Worldwide has sued Mary J. and her production company, claiming the singer agreed to perform in Dallas on December 9th, 2012 ... but canceled just a few days beforehand. VEW claims it paid Mary a $145,000 deposit to appear ... and she never paid back the money, despite pulling the plug on the show. VEW claims Blige blew them off because she got a better opportunity to perform at the Barclays Center with Mick Jagger and the Rolling Stones on December 8th ... and she took it. Unfortunately for Mary J there is video proof….she hits the stage 1:32  into the video below.

RIHANNA LATE FOR SHOW, AGAIN

 On Monday, Rihanna kepts fans in Birmingham waiting two hours before she finally hit the stage at 10:30pm, for what had been billed as an 8pm concert!  So what was the hold up? YBF.com reports that  no one has an "official" excuse, but paps did snap RiRi partying with bff Melissa Forde and model Cara Delevingne at London hotspot Bouijs at 1:45am.  And with reports that she left the club after 3am...it's natural that she would be a little tired. But there seems to be a bigger issue brewing overseas. It isn't that Rihanna simple starts her shows late.  In fact, UK critics have been panning her concerts as lackluster and boring. The London Standard said this about her recent Twickenham stop, "As her penchant for casually singing over the top of her own records at shows suggests, Rihanna wasn’t the most vigorous performer, and she looked dead-eyed …Rihanna deserves a break and so do we." Hey Rihanna, Beyonce is a tough act to follow…..

The fan tweeted last night "@JColeNC retweet me and I'll buy Born Sinner. Don't retweet me and I'll kill my lil sister." Shortly after the threatening tweet, which refers to Cole's new album ... Cole did indeed retweet the message. It's unclear if the gun is real or where the twisted fool behind the tweet actually lives. The account, which we're not revealing, claims to be out of Saudi Arabia -- but the truth is it could be anywhere in the world. TMZ  reached out to police in North Carolina -- where J. Cole lives -- to see if they were investigating ... but they hadn't heard anything about it.  We also contacted Twitter headquarters ... a rep said the company doesn't comment on individual accounts to protect privacy  This morning J. Cole commented about the incident, saying ... "Wildest s**t I ever seen on twitter." You can see the tweeted picture at tmz.com

ALLEN IVERSON KIDNAPS HIS KIDS

Ever since Allen Iverson’s NBA career went bye-bye, Iverson’s character has been called into question on several occasions. In one such instance, the judge in his divorce trail basically said he was a lousy father to his children. And now Tawanna Iverson, according to TMZ, filed legal paperwork claiming Allen Iverson recently asked for permission to take their five kids on a short vacation to Charlotte, NC from May 22nd-May 26th (and Tawanna agreed) but when May 26 came and went, the children – who range in age from 3 to 16 years old – hadn’t been returned. Tawanna — who has sole legal and primary physical custody of their children — now believes Allen never took their kids to Charlotte at all … and is currently keeping them at a Sheraton hotel in Georgia. She now wants the court to force him to return the kids and punish him in some sort of way. If you’re thinking jail time … yes, that’s what she has in mind.

Probably the one thing that hardcore Michael Jackson fans hated to admit or even talk about in the last years of his life were the constant rumors that he broke. Now, as a result of his wrongful death trial, it appears the rumors were dead on accurate. On Wednesday, AEG head man Randy Phillips told the jury about an emotional meeting he had with Jackson around Halloween, 2008.  Phillips said a tearful Jackson told him his 3 kids were living “like vagabonds” — shuttling from a Las Vegas rental to the Bel Air Hotel in L.A. In the final months of his life, one of the biggest motivators for doing the London shows was just to make enough money to buy his own home where he could raise his children.
