Lindsay Lohan has sparked speculation her engagement to Russian Egor Tarabasov is OFF after removing her emerald engagement ring.

The star, who is currently on holiday in Italy, shocked fans last weekend when she claimed Egor had cheated on her in an explosive Twitter rant.

She later backtracked and insisted she regretted making their problems public, but has now fuelled rumours it’s all over by taking off her huge rock.

The redhead was seen replacing the recognisable ring during a shopping trip on Friday in Sardinia, where she’s been for most of the week and replacing it with a new sparkler from Chopard.

She was still wearing the new bling as she arrived at Phi beach with a friend.

Dressed in a black cross-strap bikini, with a patterned fringe kimono the star was barely able to contain her ample breasts as she descended from her boat to the sand.

The question mark over her relationship comes as it was denied she’s pregnant.

Her father Michael claimed last week that she definitely was expecting and then fuelled the rumours when he later called Page Six TV to claim the star had told him the news.

Despite his claims, a source close to Lindsay – who is currently ignoring the rumours while holidaying abroad – has claimed that Michael is lying about the entire thing.

“Lindsay isn’t pregnant, she just wants a reaction,” an insider told The Sun . “Michael has a history revealing very private information from his daughter.

“But in this case he’s passing on untruths. Her inner circle just don’t believe it.”

The pregnancy claims come after the troubled star apologised for taking her private affairs public with her social media meltdown on Sunday after accusing her fiancé of cheating .

She claimed the 22-year-old Russian millionaire businessman had spent the night with Dasha Pashevkina , a woman she branded a “Russian hooker”, after he failed to come home.

She wrote in a lengthy post: “Social media comes with the territory of the business and the world we now live in. My intentions were not meant to send mixed messages. Maybe things can be fixed… Maybe not.. I hope they can.

“But I am 30 years old and I do deserve a #GENTLEgiant Life is about love and light. Not anger. Thank you to those who stand by my side.”

The Mirror has contacted reps for Lindsay for comment.
