While the actress was donning the jewellery again, there is no evidence she will be walking down the aisle anytime soon, given that the star was wearing it on the fourth finger of her right hand.
Last month Lohan accused the Russian business heir, 23, of cheating on her and suggested she might be pregnant.
Despite sharing photos of Tarabasov with his face scribbled over, and revealing to the world the name of the woman Lohan believed he was sleeping with, she then asked fans for privacy.
"I would appreciate if these speculations regarding my personal life would respectfully come to a halt,” Lohan captioned a photo of a heart-shaped cloud.
“Unfortunately, a private matter has become more public than I can control and I would be extremely grateful if my fiancé and myself could discuss our personal matters on our own."
