Lindsay Lohan is now a co-owner of a nightclub after her boyfriend Dennis Papageorgiou gave her a large percentage of ownership rights to the spot in Athens, Greece, which he has named Lohan.

The 'Mean Girls' star and her rumoured beau Dennis Papageorgiou will open the nightspot, called Lohan, in Athens, Greece, on Saturday and the pair are expecting "famous guests from Hollywood" to turn up to the launch.

A rep for the establishment told the New York Post's Page Six column: "Lindsay and Dennis are getting ready to welcome the Athenian enfant gâté, as well as Lindsay's Hollywood circle, at their new nightclub in downtown Athens."

It's not known which of Lindsay's Hollywood pals are expected to attend the launch night, but the 30-year-old actress certainly seems excited about the event.

Lindsay wrote on Instagram: "Getting ready for #LOHANNIGHTCLUB #athens"

She also posted a short video of her sharing a smooch towards the camera and captioned the clip, which had the words "this feels right" written over it, "#lohannightclub"

Dennis, a restaurant and bar owner, is known as the guy who she claims "saved her" from her ex Egor Tarabasov when he stepped in to break up a fight between them.

A source recently said: "Lindsay initially met Dennis at her 30th birthday party on Mykonos, but she only had eyes for Egor at that point.

"But Egor showed his true colours in a series of blazing rows, and Dennis did too with how he stepped in to help. Lindsay says they are very serious and she's been referring to him as the man who saved her from Egor."

Dennis is said to have dumped his long-term model girlfriend Noelle Koutra to be with Lindsay.
