Reese Witherspoon, 35, got MTV's Generation Award at the MTV Movie Awards Sunday night, and made it clear that she doesn't approve of the newest MTV generation. Witherspoon told the crowd:

    “I get it, girls, that it’s cool to be a bad girl. But it is possible to make it in Hollywood without doing a reality show. When I came up in this business, if you made a sex tape, you were embarrassed and you hid it under your bed."

Then, Witherspoon took a clear dig at Blake Lively, who presented at the awards:

    "And if you took naked pictures of yourself on your cell phone, you hide your face, people!”

Awkward! Lively's been caught up in a scandal since what are supposedly naked photos of her surfaced on the Internet. Lively's rep has called the pics "100% fake," but Witherspoon doesn't seem to be buying that. We were surprised the camera didn't cut to the Gossip Girl's face in the crowd after the comment -- maybe she had already skipped out.

Lively did not acknowledge the scandal when she and Green Lantern co-star Ryan Reynolds presented the Best Kiss award, and took no questions from reporters in the press room.

But, one celeb did acknowledge Reese's speech ... via Twitter. See who it was and what she said after the jump!
