A Motorola ad featuring Megan Fox naked in a bathtub has emerged as a popular choice for favourite Super Bowl commercial this year.
But it is not the actress's bare skin that has caught the attention of bloggers, who have taken issue with a thumb double allegedly used in the ad.
Armchair critics were quick to post comparison photos of Fox's thumbs in real life and those seen in the commercial.
PHOTOS: Super Bowl action
"Did anyone else catch this? 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," a post on the Celebrity Smack blog read.
"As you all know, Megan has got some pretty funky toe thumbs, or 'club thumbs'."
Another blogger agreed: "I haven't watched much of the Super Bowl but I did notice they used a thumb stand-in for Megan Fox's freakishly gross pair."
In the Motorola ad Fox takes a photo of herself in the bath and then ponders, "I wonder what will happen if I send it out."
Chaos is then seen erupting after husbands, partners, electricians and men on ladders receive the saucy snap.
Other Super Bowl commercials which used humour to sell a product included the Doritos ad, where a dog is seen getting his own back on a man who won't share his chips by shackling him with an anti-bark collar.
In a Coca Cola ad, a sleepwalking camper in the African wilderness somehow manages to avoid getting attacked by a wild jaguar, trampled by a herd of elephants and eaten by a giant hippo, before making it to a fridge with a cold bottle of Coke inside.
A Bridgestone commercial, set in a dark future world, shows a car being held up by a creepy-looking bald man who demands, "Your tyres or your life".
When a woman is shoved out of the car the dismayed-looking robber curses, "I said life not wife."
