Earlier this week, Kylie made headlines when she was spotted with Jaden Smith, 14, at a screening of Brad Pitt's World War Z.

The pair, who have been rumored to be dating since March, were spotted engaging in a little PDA on Wednesday at a movie theater in Calabasas, Calif.

After the two were photographed together, Kylie took to her Twitter page to rant about the paparazzi. 

"It sickens me that 5 cars of men are legally allowed to follow a 15 year old girl," she wrote.

Sending off another tweet, she added: "How is this legally allowed?" 

The two have denied they are a couple. 

Will Smith's son referred to Jenner, 15, as his "friend" in the May issue of Wonderland Magazine. "She's one of my best friends. It's pretty awesome.
