Tyson Beckford Chris Brown Feud Escalating

Chris Brown had a meltdown Sunday after Tyson Beckford dared to post a picture of himself with Karrueche Tran, Browns Ex. It started Sunday when Chris saw the photo, then posted a flurry of tweets, saying among other things, "U wanna keep walking them runways." Chris has since deleted the tweets. Tyson made it clear, he's not scared one bit, firing back, seemingly impervious to the threats, saying, "It's all about fun in Vegas, come thru papa."
