The New Mexico resident discovered that her account had been disabled for being "inauthentic" when she tried to log in, TMZ says.
Gomez - who used her full name Selena Miranda Gomez on the social network - was told that her account had been locked because "impersonating anyone or anything is not allowed".
"I am not an imposter," Gomez said. "I even put my middle name on my [Facebook] to clear up any confusion... I did not have one single famous friend. I did not refer to myself as [the famous Selena], and I did not have any pictures of her on my page."
Gomez has reportedly asked Facebook to reactivate her account but has not yet heard anything about the situation.
Facebook has not commented on the reports.
