1:24 PM PT -- Paris Hilton and Nicky Hilton are sending their well-wishes to the mom-to-be -- we got the sisters leaving CBS Studios in NYC, giving some "congratulations" to Lindsay Lohan!
1:22 PM PT -- Lindsay's ex Sam Ronson tells TMZ ... "I wish her all the best. It's always great news when someone is expecting a baby."
Lindsay Lohan and her husband Bader Shammas are starting a family ... she's got a bun in the oven.
Lindsay tells TMZ ... "We are very excited for our new family member to arrive and we are looking forward to this next chapter of our lives!"
This baby will be the first for Lindsay ... so this is a huge life milestone for the 36-year-old.
Lindsay was last photographed a little over a month ago, and she was wearing loose fitting clothes covering her belly.
Remember ... Lindsay and Bader tied the knot last year, with the announcement coming on her birthday. The expecting parents started dating just before the pandemic shut down the world, and in November 2021 she announced their engagement.
Lindsay's been through all sorts of ups and downs over her three-decade career in Hollywood, and now she's going to be a mother.
Congrats!!!
