K-Stew 'Banned' From Cosmopolis Premiere
Actress reportedly not welcome at R-Pattz red carpet event...
According to Radar Online, security staff have been told to keep K-Stew well away from the red carpet and the after party.
The US gossip website suggests that movie bosses fear Kristen may turn up in a bid to talk to R-Pattz face-to-face.
An insider told the site: "Despite the fact Robert and Kristen have been communicating by cell phone, she will not be at the Cosmopolis New York premiere.
"Security was briefed and they were told that Kristen is not allowed anywhere near the red carpet or the after party."
The US premiere of Cosmopolis is due to take place in New York on 13 August and looks set to be Rob's first public appearance since the news of Kristen's fling with director Rupert Sanders broke.
Both R-Pattz and K-Stew are likely to face an awkward reunion at the premiere of Breaking Dawn - Part 2 later this year.
