Brown. (Cindy Ord/Getty Images)Teigen. (Kevin Mazur/WireImage)Chris Brown fans have a temper as fiery as their idol. After model Chrissy Teigen, fiancée of musician John Legend, tweeted her dismay that the "Turn Up the Music" singer was lip-synching during his Billboard Music Awards performance, droves of members of "Team Breezy" inundated the model with hate messages, even death threats. "You need to be raped and murdered," one fan tweeted to Teigen, while another added, "i hope you are the next 'celebrity' to die." Some even suggested she should kill herself because "your [sic] nothing."

What did Teigen, 26, say to bring on such hate? "Why sing when you can dance?" — which didn't even mention Brown specifically. Still, his fans must have been sensitive since Brown, who is very auto-tuned on his albums, was the only person on the stage that night who clearly lip-synched his performance. And the Sports Illustrated swimsuit model wasn't the only one who tweeted about Brown's lack of vocal ability. Pink and her husband, Carey Hart, also weighed in

The Siegfried and Roy entertainer, who was nearly mauled to death by a tiger mid-show in 2003, is being accused of grabbing the buttocks and crotches of three male physical therapists hired to help him regain his strength in 2010 — and it's all caught on tape. The plaintiffs — who are suing Horn since they cannot press charges due to a one-year statute of limitations — have provided video proof of their abuse to TMZ, but the site will not post the footage due to its graphic nature.

PacificCoastNews.comAccording to Sharon Stone's former nanny, looking after her three sons was a lot less stressful than dealing with the boys' famous mother. Erlinda T. Elemen filed a nine-page lawsuit in Los Angeles Superior Court on Wednesday claiming that the "Basic Instinct" star harassed her continually during her five years on the job, especially about her "stupid" Filipino accent, and says that Stone ordered her to not speak in front of the children — Roan, 12, Laird, 7, and 6-year-old Quinn — so that they would "not talk like you." The suit also reveals that Stone, Tibetan Buddhism convert, would not allow Elemen to read her Bible while in the actress' home, and alleges that the 53-year-old actress finally fired her in February 2011 once she discovered that Elemen had been paid overtime, which she deemed as "stealing" from her, even though it was in accordance with state law.

Smith speaks out. (Splash News)Will Smith may have shocked his fans when he slapped a male reporter who kissed him on the cheek at the Russian premiere of "Men in Black 3" last week, but he's not apologizing. During his Tuesday appearance on the "Late Show With David Letterman" to promote his new movie, the actor seemed to take great pride in his actions. "We're doing an interview, right? And he says, 'I'm your biggest fan. Can I have a hug?'" Smith explained. "So I go to give this joker a hug and he, like, tries to lean in to kiss me. It's just awkward, Dave!" After the backhanded slap, the reporter's people tried to explain his actions to Smith. "They were like, 'Oh no, we're sorry. It's just his schtick,'" he told Letterman. "And I said, 'That's why his ass got schtuck.'"
