Justin Bieber was spotted ''flirting'' with Hailey Baldwin.

The 'As Long As You Love Me' hitmaker - who is rumoured to be seeing the 18-year-old model - was filmed enjoying a ''date'' with her at State Social House in West Hollywood on Friday (12.12.14).

A photographer at the scene told X17online:

''Justin and Hailey were definitely on a date. He was in a great mood - dancing, drinking, flirting with Hailey.

''She seems kind of shy, which may be one reason Bieber likes her. He's used to girls throwing themselves at him and she's just low key. She's kinda like one of the boys - but hot!''

The pair reportedly arrived at the gastropub in Justin's red Ferrari before being escorted to a private space at the venue.

The 20-year-old singer is believed to have even asked her to dance with him and whilst they were chatting, Justin was spotted biting his lip.

Meanwhile, Hailey - who is the niece of Hollywood star Alec Baldwin - recently denied the rumours that her and Justin were dating.

She said previously: ''I've known him since I was so young - since I was like 13 - and we've just been good friends over the years.

''We have just stayed close and there's nothing more to it than that.''
