I stand corrected ... (smiley)
Edited If you want to say 'I believe it' you can just say 'lo creo' - (smiley)
As our learned friends below have kindly pointed out though you can use the 'me' for emphasis.
"Me lo creo" is not exclusive of Spain. Latin American Spanish speakers use it too. Example: "De tí me lo creo todo" (About you I believe anything).
Other pronoun forms are also common: "Es muy ingenua. Se lo cree todo".
Me lo creo is used in Spain.
Remember to use the search function.
