Trouble in paradise?

Lindsay Lohan has accused fiance Egor Tarabasov of cheating -- and implied that she's pregnant -- in a series of strange social media posts.

Although many have since been deleted, here's what went down:

On July 22, the actress, 30, confirmed for the first time that she and the 23-year-old Russian businessman -- who's heir to a fortune worth billions -- are indeed engaged when she referred to him as her fiance in a Snapchat post. (Her rep had previously denied an engagement.)

"My fiance's being really angry at me, but I'm drinking water to get him to come home. Honey, come home, please," she said in the clip she captioned "ET phone home," according to People.

The following day, she shared a photo of herself and Egor on Instagram -- except his face was scribbled out. She captioned this pic, " He wore black and I wore white.... 🙉🙈🙊⚓️ I guess #art is whatever you make of it."

He wore black and I wore white.... 🙉🙈🙊⚓️ I guess #art is whatever you make of it.

In another Instagram pic of the pair she's since deleted, Lindsay tagged Egor and wrote, "I guess I was the same at 23... S----y time - it changes at 26/27. @e2505t thanks for not coming home tonight. Fame changes people," according to a screengrab captured by DailyMail.com.

She also tweeted "Home?" with a link to a now-deleted pic of Egor inside a nightclub or party and accused him of spending time with PA5H creative director Dasha Pashevkina, whom she referred to as a prostitute. "Wow thanks #fiance with Russian hooker @dasha_pa5h," Lindsay wrote before sharing the woman's home and email addresses in a tirade that also strangely included Donald Trump and Vladimir Putin hashtags, according to multiple reports.

She then deleted those.

Then came another doozy: Lindsay took to Twitter the evening on July 23 to post a link to to one of her old movie trailers with an eyebrow-raising message: "lindsay lohan labour pains trailer - I am pregnant!!"

And on the morning on July 24, she shared an Instagram photo of an unidentified woman sitting sideways in a chair with a praying-hands emoji as its only caption. "🙏🏻."

According to GossipCop, after LiLo put her man on blast, he came home in the early-morning hours of July 24 and they had an intense fight, after which he left again.

So the saga continues...
