The Mean Girls star was spotted partying with business partner and restaurateur Dennis Papageorgiou at Bouzoukia nightclub on Friday night (14Oct16), and photos have since emerged of the two sharing a kiss.

They then attended the launch of their new Lohan Nightclub on Saturday (15Oct16), with the actress spending hours mingling with revellers, snapping 'selfies', and even taking over the DJ decks for a few minutes.

Despite the images of the pair getting close, Lindsay took to Instagram on Saturday to play down the speculation over her love life, insisting, "Dennis is not my boyfriend. He is my business partner and dear friend."

Lindsay has been single since splitting from her Russian fiance Egor Tarabasov in July (16), after she accused him of cheating on her during a night out. They subsequently became involved in a heated argument at her London home, where she was caught on camera standing on her balcony, yelling for her neighbours to call the police amid claims Egor had tried to strangle her.

Egor was not arrested or charged over the incident, which Lohan, 30, later claimed was not the first time he had reportedly been violent towards her.

Her 23-year-old ex has denied the accusations, and recently declared Lindsay was embarking on a "smear campaign" to damage his reputation.

The former couple began dating last year (15) and after a whirlwind romance, Egor proposed with a four-carat emerald ring in September, 2015.
