OK, she didn't use her name -- but it was obvious at the MTV Movie Awards last night, Reese Witherspoon HATES everything Kim Kardashian stands for -- from the sex tape to the reality show.

As Reese accepted the "Generation Award," she told the crowd, "I just wanna say to all the girls out there, it's cool to be bad, I get it ... but it's also possible to make it in Hollywood without a reality show."

She added, "When I came up in this business, if you made a sex tape, you were embarrassed and you hid it under your bed and if  you took naked pictures of yourself on your cell phone, you hide your face."

Was that a shot at Blake Lively?
