Curtis poked fun at their roles in her post on Instagram.
"MAGIC MONDAY! My movie daughter just made me a movie grandmother. Blessings to Lindsay and Bader for the birth of Luai! @lindsaylohan," she wrote.
Lohan's rep confirmed Monday that the actress gave birth to a son, Luai, with Shammas."Lindsay Lohan and her Financier husband, Bader Shammas, welcomed a beautiful, healthy son named Luai. The family is over the moon in love," the rep said.
Lohan had announced her pregnancy in March.
"I spoke to Jamie Lee Curtis recently and she was like, 'You just bring the baby with you and everything will be fine," she said.
Curtis has two children, Ruby and Annie, with her husband, writer and director Christopher Guest.
