In a sweet Instagram post, the actor wrote: "We are blessed and excited!"
Alongside the caption, she shared an image of a white baby onesie with the words 'coming soon...' emblazoned across the front.
Fans were quick to flood the Freaky Friday star's social media post with good tidings to celebrate the wonderful news.
One Instagram user said: "WOWwwwee!"
A second social media fan wrote: "Congratulations."
While a third kept it simple with the comment: "Aaaaaaaaaaaaaaa."
That last one added a string of emojis with love hearts for eyes.
For added effect, of course.
And it's fair enough that fans of Lohan are thrilled for the newlywed couple.
The child will be the first for the pair, who are both 36.
And, even though some may not be familiar with the name 'Bader Shammas', he's definitely got Lohan all loved up.
The two tied the knot in July 2022 during a clandestine wedding in Turkey.
Their European honeymoon followed immediately afterward.
The pair had sparked speculation that he had put a ring on it in snaps shared to The Parent Trap star's social media at the time.
Naturally, they chose to confirm their nuptials via social media as well.
Lohan wrote on Instagram: "I am the luckiest woman in the world. He found me and knew that I wanted to find happiness and grace, all at the same time."
She added: "I am stunned that this is my husband. My life and my everything. Every woman should feel like this everyday."
Fans were thrilled to see Lohan happy, with many taking to the comments section to congratulate her on finding her special someone.
One user said: "You look so beautiful and happy."
A second added: "What a gorgeous couple you both make."
While a third commented: "Lindsay, you deserve this for the years of struggle. I'm glad you're in a good place."
After dipping out of the spotlight for a few years after some issues with her mental health, Lohan rose from the ashes of her career like a Phoenix to churn out a cheesy yet smash-hit Netflix movie Falling for Christmas in November.
The happy couple also made their red carpet debut at a New York screening for the film, marking the star's return to Hollywood.
Good for you, gal.
Now let's just hope it's not twins. Otherwise we could one day have a real life version of The Parent Trap on our hands.
