The Oscar winner—who played Lindsay's mom in the 2003 comedy—congratulated the actress on her pregnancy in an April 27 Instagram post. Resharing the 36-year-old's photos from her recent baby shower, Jamie Lee wrote, "My friend and film daughter @lindsaylohan is growing up!"
"So thrilled for her," the 64-year-old continued. "What a mama she will be."
On her own Instagram page, Lindsay posted pictures of herself craddling her growing belly at her baby shower. One image showed the Mean Girls alum clad in a white dress, while she was snapped rocking a fringed orange frock while posing with her sister, Aliana Lohan, in another shot.
Guests at the intimate gathering also included Lindsay's offscreen mom Dina Lohan and stylist Juliet Angus.
"Good times," Lindsay captioned the photos. "So grateful for all of the wonderful people in my life!"
It's been almost 20 years since Freak Friday was released in theaters. Based on Mary Rodgers' 1972 novel of the same name, the flick starred Jamie Lee and Lindsay as Tess and Anna Coleman, a mother-daughter duo who switch bodies after cracking open a mysterious fortune cookie.
In December, Jamie Lee told E! News that she and Lindsay are "all down" for a sequel.
"It's not up to us right now," the Everything Everywhere All At Once star added, "but I think everyone who needs to know knows, and clearly we are in conversation."
Maybe they'll swap bodies with a baby this time?
