25-year old Vietnamese model Karrueche Tran showed off her unusual leg tattoo on the pink carpet Saturday. The event was Zing Vodka's Kandyland soiree and was held in Beverly Hills, says the Daily Mail.

Tran delighted many photographers who sought the opportunity to take photos of her highly emphasized leg tattoo. Wearing a Kimi Kouture red romper and gladiator heels, Chris Brown's on and off girlfriend flaunted the long zipper tattoo.

The zipper tattoo runs on her right leg from below the buttocks to her right calf. Tran also has five other tattoos in the form of sayings and quotations.

Tran's on and off boyfriend, Chris Brown, who recently suffered from seizures, was not spotted at the event. News broke out that the 24-year old musician had to cancel concerts due to health-related and "personal" issues.

According to the NY Daily News, the singer was set to perform in at least four Canadian cities from Aug. 29 to Sept. 1. Brown was scheduled to headline the Energy Rush Festival in Halifax, Toronto, Saint John and Winnipeg, says CBC News Canada.

Drop Entertainment Group owner Stephen Tobin released an official statement regarding the pull-out:

"After ongoing conversation and consultation with this year's headline act Chris Brown, and in light of the performer's recent personal and health-related issues, a decision has been made to cancel all four scheduled performances."

Last week, the singer was also asked to do an additional 1,000 hours of community service in light of the recent "hit and run" incident he was allegedly involved in.

This isn't the first time Brown has been involved in legal court matters. In 2009, Brown was also taken to court by ex-girlfriend Rihanna for allegedly assaulting her.

Rumor has it that Brown and Rihanna have been secretly seeing each other for well over a year. Things blew out of proportion when Tran officially started dating Brown in January, says Anything Hollywood. Twitter accounts of both Tran and Rihanna have been quite busy ever since -- even citing the Angelina-Brad-Jen love triangle. Chris Brown's representative denied the issue saying the singer is not cheating and that he and Rihanna are "just friends."
