Megan Fox is known for her sex appeal. Men everywhere have flocked to see the Transformers movies, apparently for the action but the real reason of course is Ms. Fox.

She is expecting her first child with husband Brian Austin Green and she is absolutely glowing!

How adorable does she look in this relaxed bikini shot?!

A source tells Us Weekly Green is very protective of Fox, “He's always walking in front or behind her to make sure she is completely looked out for. He really wants to take care of her and make sure she is as happy as can be."
