And we've now been receiving various emails and messages that Heidi did in fact check in to Cedars-Sinai Medical Center and is ready to give birth to a baby girl.
Even her friend, former Dutch model Anouk Smuldersm, mentioned the happy news on Dutch TV.
This will be Heidi's fourth child, and her third with hubby Seal.
We can't wait to see those first baby pics!
