No, it wasn't the stripped-down Fox that piqued people's interest (we've happily all seen that before). It was the fact that she used a hand double in the ad...
"Yeah, so?" sassed a member of Megan's team, when we asked if M.F. really was that worried about her hands.
Remember, she has a genetic condition, brachydactyly, which means she has clubbed thumbs. Hey, we all have flaws! I think most gals would put up with funny-looking fingernails in exchange for M.F.'s looks.
But Megan doesn't see it that way.
"Obviously she's self-conscious as much as the next person," adds Foxy's pal. "Just because she's comfortable playing that femme fatale in the media doesn't mean she's really like that."
Uh-huh, back to the whole "Megan's shy" thing. We remember.
Still, Megan's "very guarded" in many aspects of her life.
That's a big reason why Meg put down the big bucks (almost $3 million, to be exact) for her new Mediterranean home that comes with lots of security. The home is walled, gated and already set up with a state-of-the-art security system.
"The fame thing still makes her uncomfortable," dishes our insider.
The 5,200 square foot Hollywood home boasts five bedrooms, four bathrooms, a gourmet kitchen, master suite with walk-in closet, private terrace and a spa-like bathroom with Carrara marble, designer toilets and a free-standing soaking tub.
So could the extraspacious new digs be 'cause M.F. is ready to settle down with on-off boyfriend Brian Austin Green and maybe start a family herself? After all, we know how fond she is of Brian's kid, so Mommy Megan really doesn't seem that much of a stretch.
"Uh, no," fesses the friend. "Like you said, they're always on or off. I'm not even sure what they are at this point. They take it as it comes."
