'OMG OMG OMG!!!!' Celebs go tweet-happy over UFC 168 madness

Dozens of celebrities sounded off on Twitter following UFC 168's gruesome ending Saturday night.

Anderson Silva'€™s visible broken leg caused plenty of emotion in Hollywood and beyond.

Fellow pop star Demi Lovato couldn't believe it, either . . .

Actress Mandy Moore and the people she watched the fights with were stunned.

Rapper Ludacris was more concerned with his wallet.

Actress/model Olivia Munn had one of the best seats in the house and captured an incredibly candid pic of Silva being carted off.

Silva'€™s injury definitely hit home in the sports world, too. Tim Tebow issued prayers for the former UFC middleweight champion and congratulated Weidman.

Former Indiana Pacers star Reggie Miller took it arguably the worst, tweeting "€œOMG" multiple times and also sending out prayers for Silva. Michael Strahan also weighed in.

TV personality and celebrity chef Anthony Bourdain saw —€“ and heard -€— the whole horrible scene in person.

Ronda Rousey'€™s women's bantamweight title defense against Miesha Tate also got some love from the celebrity set. Comedian David Spade has a lot of respect for Tate'€™s resilience.

MLB stud Bryce Harper might have a little bit of a crush.

Rousey'€™s girl power was big with actress Rosie Perez.

And then there was The Rock, who called Rousey his "€œpartner in crime."€ She also happens to be his "Fast & Furious 7" co-star.
