Niki Taylor's family continues to expand – baby no. 4 is on the way in mid-November!
The model, 36, made her big announcement Wednesday via Twitter
, posting a message that read, "Guess what's in this photo?" attached to a picture of Taylor holding an ultrasound image.
She quickly followed that note with a second photo of herself kissing husband Burney Lamar as he holds their daughter
Ciel, 2, writing, "YES!! We are expecting our fourth child! So happy and blessed!"
Taylor and race car driver Lamar, 30, wed in Dec. 2006
. The model is also mom to identical twin sons
Hunter and Jake, 16, from her previous marriage.
