CONRAD MURRAY: Dr. Conrad Murray, Michael Jackson's personal physician, has pleaded innocent to the charge of involuntary manslaughter in the U.S. pop star's death.
TMZ said Murray entered the plea Tuesday during his arraignment.
"Your Honor, I am an innocent man," Murray told Los Angeles County Judge Michael Pastor. "I, therefore, plead not guilty."
Murray's trial is set to begin March 28.
The cardiologist is accused of causing Jackson's death by improperly administering sedatives and anesthesia in an effort to help the singer sleep.
Jackson died at age 50 from acute propofol intoxication June 25, 2009.
LARRY HAGMAN: Television icon Larry Hagman says he has agreed to reprise his role of oil baron J.R. Ewing in TNT's planned new version of "Dallas."
The nighttime soap originally ran from 1978 through 1991.
"I haven't signed any contract but I gave them my commitment verbally," Hagman, 79, told TVGuide.com about his plans to appear on the new "Dallas." "I just told them I'd do it and my word's good!"
The television industry news Web site said Monday the pilot for the reboot of the series shows Hagman's character confined to a mental asylum in a near catatonic state.
"Whatever they want is OK with me," the actor said. "Oh, I'll get out and cause more trouble! That's for sure!"
KE$HA: DAS Communications, Ke$ha's former manager, has filed a $14 million lawsuit against the pop singer in New York's Manhattan Supreme Court, records show.
The firm accuses the 23-year-old recording artist, whose real name is Kesha Rose Sebert, of refusing to pay it according to her contract.
The New York Post reported Tuesday the management company's lawsuit describes Sebert as "a very young and inexperienced artist whose 'star' may not continue to rise."
"Although she has made an incredible amount of money in a very short period of time, in large part due to DAS' efforts on her behalf, she could just as easily lose money if not properly guided," the Post quoted the court papers as saying.
Sebert's hits include "Tik Tok" and "We R Who We R."
