Lindsay Lohan has fuelled speculation she is dating Max George after posting a picture of them together.
The 'Liz & Dick' actress posted a photo of her and The Wanted singer together on her Instagram account in which Lindsay, 26, is seen holding up a camera while making a peace sign with her fingers, as Max, 24, grins behind her.
Despite the picture adding fuel to the rumours they are an item, the 'Chasing the Sun' singer again denied he is romantically involved with the 'Mean Girls' star on Twitter on Monday (21.01.13).
One fan tweeted Max that she would ''die'' if he dated Lindsay, to which he responded: ''I'm not so you're fine!:) x (sic)''
It isn't the first time the pair have caught attention on social media; Lindsay previously posted a picture of Max's hoodie, tweeting to him: ''Missing something?''
The stars have been seen together several times since November 2012 when Lindsay got into a fight with another woman in a New York Club, allegedly over the boy band singer.
In December, Max said: ''It's fun, she's a good girl. She can party nearly as hard as we can. I'm sure she's got people around her that know much better than we do. We're probably not the best influences.''
Max is joined in the boy band by Siva Kaneswaran, Jay McGuiness, Tom Parker and Nathan Sykes.
