Lindsay Lohan is expecting a baby.

The "Mean Girls" star made the announcement on Instagram on Tuesday morning with a picture of a white onesie with the words "Coming soon…" printed on it. 

A rep for the actress also confirmed the news to Fox News Digital.

This will be Lohan's first child.

"We are blessed and excited!" the 36-year-old, who married financier Bader Shammas last year, captioned the post, tagging Shammas. 

She announced her marriage on Instagram last July, writing, "I am the luckiest woman in the world. Not because I need a man, but because he found me and knew that I wanted to find happiness and grace, all at the same time."

"I am stunned that this is my husband. My life and my everything," she added.

In November 2021, Lohan shared their engagement news.

"My love. My life. My family. My future. @bader.shammas #love," she captioned a post alongside photos of the two of them showing off her ring. 

Lohan started her acting career as a child and got her breakout role playing scheming twins Hallie and Annie in Disney's "The Parent Trap" in 1998.

Following movies like "Freaky Friday" with Jamie Lee Curtis, Tina Fey's "Mean Girls" and "Confessions of a Teenage Drama Queen" in the early 2000s, Lohan stepped away from the spotlight amid struggles with legal and substance abuse issues.

In 2014, Lohan left the United States and relocated full-time to Dubai. She turned her focus to entrepreneurship and opened three beach clubs in Greece between 2016 and 2018. In 2019, she starred in the MTV reality series "Lindsay Lohan's Beach Club."

She told Emirates Woman in 2018 that moving to Dubai afforded her "a fresh start."

"I moved here for that purpose. I don’t have to be publicly seen all the time or discuss what I’m doing," she said. "I get more work done because I don’t have the scrutiny and fixation on what I’m doing every second. I work all the time; my mind never stops."

Last Christmas, however, the actress starred in her first major role in a decade, joining the holiday romance movie craze in Netflix's "Falling for Christmas."

"For me, my whole life, acting is like riding a bicycle. It’s just in me," Lohan told the Hollywood Reporter last year.

"Doing films, playing a character, it brings me so much joy to be able to share a story with people. To take people on that journey with me is such a blessing."
