Don't mess with Miley. After the celebrity blogger insinuated on his website that the 20-year-old singer got cozy with Ed Westwick while engaged to Liam Hemsworth, the former Hannah Montana star took to Twitter to slam Perez. "@perezhilton hope you find love one day but can you not f--k with mine," the pop star tweeted. She later told E! News she would "whoop his ass" if the gossip columnist spread rumors about her relationship again.
