These boots were made for walking … over Tyga! A reportedly single Kylie Jenner stepped out last night — and made a serious fashion statement in bright purple thigh-high boots.

Supporting her friend Anastasia "Stassie" Karanikolaou at the launch of her campaign with PrettyLittleThing, the 19-year-old rocked the bold Balenciaga footwear with an oversized white tee with silver embroidered sleeves.

She even shared a photo wearing her outfit in the backseat of her car on Instagram, captioning the look with a purple devil emoji.

Her BFF wore a powder blue mini dress with sweetheart neckline and nude heels to her big event, which also attracted Christina Milian, Bachelor star Corinne Olympios, and rapper Travis Scott.

Meanwhile, Tyga, 27, was put in handcuffs as he was leaving a Hollywood nightclub after being pulled over for running a stop sign and not having a proper license plate on his car.

The "Rack City" rapper passed a DUI test that was administered at the police station, according to E! News and walked away with a ticket for driving without a driver’s license or insurance. He was not formally arrested or charged with a crime.

This is not going to help him win Kylie back, who reportedly broke up with Tyga over money.

"It looks like Kylie HAS finished with Tyga, at least for now anyway,” a source told Hollywood Life. “She changes her mind like she changes her underwear though and Tyga has a habit of always managing to sneak his way back into her bed somehow.”

The insider continued, "Kylie isn’t seeing anyone else, and she doesn’t think he was cheating, but she’s confident she can land herself a hotter, richer boyfriend.”
