"My fiancé's being really angry at me, but I'm drinking water to get him to come home. Honey, come home, please," she said, captioning the video "ET phone home."
The social media rant continued on Saturday, with Lohan posting a photo of her and the Russian business mogul on Instagram with his face scribbled out. In another picture of the couple, the caption read, "I guess I was the same at 23… Sh*tty time - it changes at 26/27."
It continued, "@e2505t thanks for not coming home tonight. Fame changes people."
Not long after, Lohan posted a snap of Tarabasov at a party. She wrote, "Wow thanks #fiance with Russian hooker @dasha_pa5h," tagging Dasha Pashevkina, the creative director of PA5H.
Another post also accused Tarabasov of cheating. She captioned a video of her fiancé partying with the caption, "Home? First time in my life-bare with he/ he cheated on me with hooker."
Lohan then tweeted what seemed to be personal information of the woman with her fiancé, but deleted it shortly after.
Lohan continued her posts with a shocking tweet implying she was pregnant. She posted a link to the poster of her 2009 film Labor Pains, in which she plays a woman who fakes a pregnancy before getting pregnant for real, on Twitter. The caption read, "Lindsay lohan labour pains trailer – I am pregnant!!"
Most of the posts were later deleted from Lohan's social media pages.
Since moving to London in 2012, Lohan has been more at ease, according to insiders. Sources tell WHO she's kept a lower profile and is enjoying spending time with family, friends and of course, Tarabasov.
"She's not partying as much like she used to," a source revealed. "She's doing really well and she is taking cooking classes with some girlfriends ... She has been happy staying out of the public eye. She likes staying in and flying under the radar and staying out of trouble."
