Paris Hilton is dating Josh Upshaw after splitting from River Viiperi

The blonde beauty first met her new love interest, 28, during DT Model Management's second anniversary bash at Pump restaurant in West Hollywood on Thursday night (24.07.14).

A source told E! News: "He's so nice and sweet. He's also a little older so that's good for Paris."

Asked about her romance with Spanish model River, the insider said: "That ended a while ago. Paris is happy and busy working."

The 'Stars Are Blind' singer first sparked rumours her romance with River was on the rocks when she was spotted flirting with Justin Bieber, 20, and sitting on his lap in a nightclub in Cannes, France in May.

An eyewitness said at the time: "Paris had a private table above the DJ setup at the nightclub and was clearly loving being out and being the centre of attention. She was trying to dance sexily and looked really up for a party."

The former reality TV star started dating River in September 2012 and previously insisted he was a great boyfriend.

Earlier this year, she gushed: "He [recently] made me a really beautiful piece of art, and he wrote me a beautiful letter. He does sweet things all the time."
