It's official -- Megan Fox is now a MILF.

The 'Transformers' actress and her husband, '90210' actor Brian Austin Green (yeah, we're not sure how that happened either), welcomed a baby boy named Noah Shannon Green on Sept. 27.

Considering the couple kept completely quiet about the state of her uterus even as it became clear something was in there, it's no wonder it took almost a month for the actual birth announcement to be made public.

The private couple's reps had no comment, but in a neat trick, Fox managed to speak without insulting anyone when she took to her Facebook page on Wednesday to share the news:

We have been very lucky to have had a peaceful few weeks at home, but I would like to release this myself before others do. I gave birth to our son Noah Shannon Green on September 27th. He is healthy, happy, and perfect.

We are humbled to have the opportunity to call ourselves the parents of this beautiful soul and I am forever grateful to God for allowing me to know this kind of boundless, immaculate love.

Thanks to those of you who wish to send your positive energy and well wishes. May God bless you and your families abundantly.

The duo are are already parents to Green's son Kassius from his prior marriage, so Fox probably feels right at home with a house full of boys.

Congrats to everyone involved.
