The 18-year-old reality star was visibly shaken when an unidentified person appeared to pull her hair at the Honda Center in Anaheim, California, where Tyga performed with Chris Brown.
TMZ posted footage of the incident which shows Kylie's head snap back and a grimace appear on her face as her fluorescent green locks are pulled from behind her.
The website reports that the 'Keeping Up with the Kardashians' star's security team quickly stepped in as Kylie made her escape with Tyga.
Meanwhile, Kylie squashed another ongoing drama in her life after actress Jessica Alba revealed she was shoved by the young starlet's bodyguards at New York Fashion Week.
The youngster sent the 'Sin City' actress a bouquet of flowers to apologise for the unfortunate event.
Jessica, 34, posted a picture of the ''beautiful'' bouquet on her Instagram, writing: ''Wow! Came home to the most beautiful flower tree I've ever [seen]! Thank you @kyliejenner you are a sweetheart!! So thoughtful. (sic)''
Earlier this week, the actress opened up about the ''shocking'' incident on 'Watch What Happens Live' with Andy Cohen.
Jessica explained: ''I got like body checked. Yeah, and it was like, by two of them. I was like, 'Whoa, whoa! What's happening?'
''I thought there was like a fire. Like, I was like, 'What's going on?''' she recalled. ''Um, but I guess someone was just leaving the building.''
She added: ''It was shocking.''
