Alexandra Burke Gets Blacklisted by Rihanna

Britain's X-Factor winner Alexandra Burke has it hot for Chris Brown, but Rihanna ain't having that!

Recently Rihanna has this chick banned from an after-party at London's O2 Arena. Alexandra invited her entire crew to party it up at the after party and finally fulfill her dreams of meeting Chris.

Well smiles turned to frowns real quick when Alex was turned away at the door, sources say,

"Alex was mortified. She had no idea she had been banned from meeting her idol. She’s a massive fan of Chris Brown – she said numerous times on The X Factor how much she fancies him and wants to meet him."

Don't mess with Lil Miss Sunshine's man! You will get blacklisted.
