I'm being totally serious when I say that upon seeing this picture of Lady Gaga boarding (or working at) an airline this morning I honestly thought it was Christina Aguilera. Actually, I wouldn't be suprised if Gag and Aguilera were secretly the same person. I mean, have you ever seen the two of them in the same place at the same time? You haven't have you? And so the legend lives on... I know Xtina goes all coo-coo bananas at the very mention of Lady Gahhhgs, pleading the fifth and spewing out that whole "Who that bitch is?!?" bull**** routine of hers, but we all know she's heard of the chick. By this point who hasn't, right? Fans of both singers have chosen...
