Megan Fox -photos of sons on 'Ellen"

Megan Fox is still a fox even if she had two children "16 months apart."

"The first time I was here I was pregnant, and no one knew it," the 27-year-old actress told "The Ellen DeGeneres Show" Monday.

"Then the second time I just had my baby," she continued. "But I got pregnant again so you're sort of like a fertility good luck charm."

"Ah, yes. My show is an aphrodisiac," DeGeneres quipped before asking, "So, the new child is a girl?"

Fox and her husband, actor Brian Austin Green, welcomed their second son, Bodhi Ransom Green, on Feb. 12, TMZ reported.
