Congratulations are in order for Lindsay Lohan!

The actress's beau, Egor Tarabasov, 22, popped the question over the weekend, according to TMZ -- and she said yes!

The pair began dating five months ago after meeting through friends and clearly fell fast in love. They made their social media debut on Lohan's Instagram this winter. In the snap, Lohan, who is 29, is rocking a sexy white, low-cut dress as the Russian heir, clad in a sharp tux, leans toward her.

Before that, Tarabasov spent the holidays with the Lohans in New York. Lohan's mom, Dina, recently gave her future son-in-law her stamp of approval and weighed in on their seven-year age difference.

"Yes, he is cute. He's a sweetheart. No, he's just a really good person. And the tabloids are like, 'Oh, he's so much younger.' But he's very mature, very worldly," she told Us Weekly. "They love each other."

Best wishes to the happy couple!
