One Direction star Harry Styles is reportedly cheating on model Kendall Jenner.

Styles is said to have spent a night with fashion stylist Pandora Lennard, 27, even though he is currently dating Jenner, reports femalefirst.co.uk.

"Everyone knew they were attracted to each other and they have been pals for a while. But we didn't think anything would happen as Harry and Kendall are officially an item. This is gobsmacking,” The Sun newspaper quoted a source as saying. 

Lennard is the founder of the Anti-Agency modelling company and has worked with famous faces like Little Mix, Fifth Harmony and Jessie J.

Asked about her reported fling with Styles, Lennard said: "I have absolutely no comment to make."
