"#teamwork what a blessed and calm birthday with my partner for life @thlifeofscott," Lohan wrote, referring to her friend and manager Scott Carlsen, who arranged the party.
The actress was also presented with a yacht-shaped birthday cake, and shared a photo to her Instagram story.
Carlsen also shared a sweet message for the Sick Note star
alongside a photo of them enjoying a helicopter ride together.
"Happy birthday to the best @lindsaylohan [heart] you forever. Xoxoxo," Carlsen wrote in the caption. " thank you - excited for what's to come :)"
Lohan later shared some more love with Carlsen with a close-up snapshot of the two of them wearing what appear to be white headscarves, which she captioned with a simple heart emoji.
Last week, Lohan took to Twitter to share some b-day invites with a few celebs, including Britney Spears, Paris Hilton and Beyonce.
