The Mean Girls actress 'came out' as bisexual in 2008 after she struck up a tumultuous relationship with DJ Samantha Ronson.
The on/off romance came to an end last year (09) and she's since been linked to numerous eligible bachelors including Gerard Butler, Kevin Connolly and Jason Segel.
And according to Britain's Daily Mirror newspaper, the star found a new disc-spinning partner in London - after she was spotted getting cosy with Geno during a gig at the British capital's Sketch club on Wednesday (03Mar10).
The pair was spotted flirting in the DJ booth while she played tracks for revellers, reports the publication.
But Lohan has shrugged off the suggestions, telling GossipCop.com, “No I am not (dating him). He’s a friend, geez.”
