Katy Perry rocks tiny shorts and slutty boots at Charli XCX and Troye Sivan's concert

Katy Perry delivered a stunning performance as she spent an evening watching Charli XCX and Troye Sivan during their Sweat Tour.

The 39-year-old pop singer wore a pair of tiny studded denim shorts and statement boots as she attended the performance at the Kia Forum in Inglewood, California on Wednesday night.

Katy's thigh-high leather boots clung to her legs, while her black denim shorts were decorated with metallic studs.

The star, who will be touring next year herself, teamed the look with a fitted scoop-neck top and a leather jacket that dangled from her arms.

Her raven black hair was swept across her head while her complexion glowed with smoky eyes, pink blush and pink lip tint.
