Hilton, Grenier spotted together again

Rumours about a relationship between Paris Hilton and Entourage star Adrian Grenier have resurfaced after the pair were spotted together at Louis Carreon's gallery opening.

The pair were seen swimming together and attended the premiere of Leonardo DiCaprio's new documentary 11th Hour with each other earlier this week.

A report on E!Online now claims that the duo were showing very friendly body language to each other at last night's gallery opening.

Hilton and Grenier apparently stood chatting in the hallway flirting with each after the event. Paris reportedly twirled her hair and flounced her flirty butterfly dress, while the actor smiled and had his legs open to The Simple Life star.

They then reportedly downed tequila shots and went for a meal together before attending an after party at Les Deux.
