London, June 9 Lindsay Lohan was recently spotted flashing a "wedding ring" during her visit to London, adding fuelling rumours that she has re-united with lesbian lover Samantha Ronson.

The 'Mean Girls' star was on a low-key trip to the U.K., at the same time when Ronson was in London for a series of DJ gigs.

And gossip mills starting running when Lohan hit the city's clubs on Saturday evening, proudly showing off a gleaming band on her ring finger as she left the Bungalow 8 nightspot.

"Lindsay has gone to extraordinary lengths not to be photographed with Samantha during their visit to London, but after a few drinks she clearly let her guard down. She was holding her hand up for the cameras to get a clear shot of the ring and didn't seem to care who noticed," the Daily Star quoted an onlooker as saying.

Lohan and Ronson split in March after a series of furious bust-ups. (ANI)
