At her side was her rumored fiancé, Egor Tarabasov, who got emotional when he addressed the birthday girl in a speech before their guests, calling her "the most important thing in my life" - a moment stylist Julie Tangus caught on video and shared on Instagram.
In addition to the heartfelt dedication from Egor, the festivities included some table dancing (because Greece):
At another point during the party, pals like Lindsay Lohan's "Freaky Friday" costar, Jamie Lee Curtis sent her birthday wishes via video:
"The really good news about getting older is that you're so old now, we could do a remake of 'Freaky Friday,'" Jamie says in the clip, implying Lindsay could be the mom in a revamp of the 2003 flick.
The party finally wound down, but that apparently wasn't the end of Lindsay and Egor's romantic getaway.
(LiLo's mom, Dina Lohan, reportedly missed the party due to an unknown illness that had her hospitalized last week.)
"My baby is cooking for all of us on another beautiful day filled with#LILOIS30 #loveandlight 🙏🏻 amen," she captioned a pic of Egor, standing shirtless before an outdoor kitchen setup.
Lindsay and her 22-year-old Russian businessman beau have reportedly been living together in London since shortly after she introduced him to her folks in New York over the holidays.
In April, LiLo was photographed with aq 5-carat emerald ring on her left ring finger. Though her rep initially denied she was engaged, friends have confirmed the actress' wedding plans to multiple publications.
