Megan Fox, who flew well below the Hollywood radar while expecting her second child with husband Brian Austin Green, has given birth to another baby boy.

While the new tot's name and other vitals like weight, length or a picture have not yet been released by Fox and Green, we do know Baby Boy Fox-Green was born on Thursday, according to TooFab.

He joins older brother, Noah, who was born in September 2012. Fox, 27, did not reveal her firstborn's arrival until a few weeks later. She is clearly a very protective mama bear.

Green, 40, is also father to son Kassius, 11. His mom is actress Vanessa Marcil.
