R&B star Chris Brown has vehemently denied new allegations of assault after he was accused of shoving a woman in a California nightclub on Saturday (22Jun13). Deanna Gines claims she had been partying with the Kiss Kiss hitmaker in the VIP section of the Heat Ultra Lounge, following his performance at the nearby Powerhouse 13 concert, when the singer violently pushed her to the ground. The 24 year old, who is said to have suffered torn ligaments in her right knee as a result of the altercation, filed an official complaint with the Anaheim Police Department on Sunday (23Jun13). She also shared a photo of herself using crutches, with her leg in a brace, on TMZ.com. Brown, who is on probation for his 2009 assault on his then-girlfriend Rihanna, has lashed out at the report and personally reached out to editors at TMZ to "stop with the false stories". In a post on Twitter.com, he added, "I don't usually comment but I didn't do anything. Had a great show at powerhouse and a positive one." He subsequently deleted the messages and replaced them with the tweets, "postive energy... The devil is always working. If it wasn't for my faith and my fans, I would've quit music along (sic) time ago. I'm tired of it man....! stay positive". Anaheim Police are currently investigating the latest assault allegations. Brown has notoriously struggled to keep his temper under control - he became embroiled in a fight with rapper Drake during a night out in New York last year (12), and he was allegedly involved in a car park bust-up with singer Frank Ocean in January (13).
