London: Troubled actress Lindsay Lohan has fuelled rumours of dating German fashion designer Philip Plein after they were photographed walking hand-in-hand in Milan.

Lohan, 25, was snapped laughing with Plein as they strolled hand-in-hand around the city, while she was also seen taking a ride with him in his Ferrari, according to reports.

The 'Mean Girls' star has signed up as the face of Plein's designs and was spotted taking part in a photoshoot for the brand in Bellagio before the partnership was officially announced during Milan Fashion Week on Sep 24.

Whereas Lohan claimed she met Plein for the first time on September 23, but they appear to have grown close as they were photographed holding hands during a shopping trip this week.
