Caroline Flack was harassed by One Direction fans after dating Harry Styles but the 32-year-old 'cougar' is still hanging out with his band-mates.

Caroline partied with 1D's Niall Horan at the UKs V Festival on Sunday, posing in a series of Twitter pics with the 18-year-old heart-throb.

The pair got playful for the camera alongside British singer Tulisa and her personal assistant Gareth Varey, who posted the shots online.

The Xtra Factor host made no effort to hide the fact she's keeping company with Niall, re-posting the pics on her own Twitter feed.

Caroline and Harry must be on fairly good terms if she’s hanging out with Niall but we can’t help wonder, has the 32-year-old got a thing for young guns?
