Weeks after Lindsay Lohan and fiance Egor Tarabasov professed their love for each other at the actress' 30th birthday party, it seems there may be trouble in paradise.

Lohan took to social media on Saturday to air out some possible relationship drama in a series of posts.

"I guess I was the same at 23. S---ty time- it changes at 26/27," she wrote, along with a snap of herself and Tarabasov. "@e2505t thanks for not coming home tonight. Fame changes people."

Moments later, the "Mean Girls" star posted another photo, this time of Tarabasov at a party.

Next came a video of her fiance in a club, which she captioned "Home?"

And an hour later, LiLo followed up with this bombshell of a tweet, seemingly implying she's pregnant.

ET has reached out to Lohan's rep for comment.

Lohan and Tarabasov met last summer; Tarabasov popped the question to the former child star in April. Soon after news broke of the pair's engagement, Lohan's father, Michael, gushed to ET about her relationship.

"I'm so happy that Lindsay has found true happiness," he said. "It's written all over both of them."

Just days ago, the couple seemed more in love than ever, as they frolicked around Greece, posting sweet snaps of each other on social media.
