AceShowbiz - Lindsay Lohan finally showed off her baby bump. The "Mean Girls" actress, who is expecting her first child with husband Bader Shammas, flaunted her growing belly in a mirror selfie that she shared on Instagram Story.

In the Tuesday, April 25 post, the 36-year-old pregnant beauty could be seen pursing her lips together as she posed in a green-and-white knit maxi dress. The said picture was taken during her stay at The New York Edition hotel.

Lindsay confirmed she's having a bun in the oven back in March. At that time, she unleashed a snap of a white baby onesie that read "coming soon..." In the caption, the expectant mom gushed, "We are blessed and excited! [prayer, heart and baby emojis] (sic)."

It was unveiled earlier this month that Lindsay and Bader celebrated her pregnancy with family and friends at a party. Following the bash, a source told Us Weekly that the actress is "happier" than she has ever been since discovering that she is to become a mother.

"[Lindsay] loves being pregnant. She's the happiest when she's with her closest friends and family," the source told Us Weekly. "She is rarely in town for long, so friends and family wanted to celebrate. It was very private - just a handful of close friends and family having brunch in honor of Lindsay’s pregnancy."

The insider went on to hint to the outlet that a "bigger" celebration for Lindsay is set to take place where she lives in Dubai. Meanwhile, the expectant star has spent her time in New York with her family looking for clothes for both herself and the baby.

"During the short trip to New York, she also spent some quality time shopping with her siblings for baby clothes and cool and stylish maternity clothes," said the source.
