"It's just me [under there]. It's terrifying," the British star tells Ellen DeGeneres during his Tuesday interview, after the Ellen host asked about his nicker situation -- or lack thereof.
And despite him being male, the Social Network star admits that he's shy about his body just like his female friends.
"One of the first nights we were out in location in downtown L.A. in a parking structure and I knew there were paparazzi taking terrible, unflattering shots of my, you know, everything," he tells DeGeneres. "Knowing that your keester is being shot from many different angles makes you very uncomfortable."
DeGeneres sympathized with the the 28-year-old actor by saying, "no one wants their keester shot from an angle," before presenting him with a disguise so he can go incognito once the Spider-Man reboot hits theaters.
Garfield tried on the blonde moustache and matching mullet wig and sunglasses, adding that the look made him feel "German."
The Amazing Spider-Man, in which Garfield stars opposite real-life love Emma Stone, hits theaters Fourth of July weekend.
