If Motorola’s Superbowl commercial proved anything Sunday night, it’s that there are one too many bloggers out there who are overly familiar with Megan Fox’s body parts – especially her thumbs.

The commercial features the sexy “Transformers” star au natural in a bathtub filled with strategically placed bubbles.

According to the Daily Mail, after the commercial aired, meticulous bloggers noted that Motorola employed a hand double for Fox’s closeups.

“Did anyone else catch this?” wrote a blogger for Celebrity Smack. “I couldn’t help but chuckle when they showed a close-up of the Motorola phone and the hands holding it were definitely not Megan Fox’s.”

After Fox’s promotional movie photos surfaced last summer, revealing a candid look at her abnormally shaped thumbs, the Daily News learned that the 23-year-old actress has a hereditary defect known as brachydactyly.

“Literally, what it means is short finger,” Dr. Steven Bendner, a hand surgeon at Beth Israel Medical Center, told us. “The nail of the thumb in this condition is often very short and wide.

“It is usually hereditary. Although it could also have been caused by frostbite, or it could have been an injury to the growth plate in childhood.”

But don’t expect Fox’s so-called clubbed thumbs to stand in the way of her career anytime soon.

“In Megan Fox’s case, it appears that only the last bone of the thumb is affected and that it does not involve the joint,” says Dr. Richard Kim, director of congenital hand surgery at Hackensack Medical Center. “For her, it looks like it’s just a cosmetic deficit.”
