On April 21 in L.A., Ross Bagdasarian Jr., 59, the son of late Chipmunks creator Ross Bagdasarian Sr., sued 20th Century Fox, claiming that he and his wife, Janice Karman, 53, are owed half the profits from Alvin and the Chipmunks: The Squeakquel. The couple says the screenplay for the recent hit, which grossed $442 million worldwide, borrowed large portions of a preliminary script by Karman. They also claim that the studio hasn’t sufficiently merchandised the Chipmunks brand. In a statement, Fox says the claims are ”completely without merit.”

Rapper Guru, 48, passed away April 19 in Suffern, N.Y., after a battle with cancer. As the vocal half of the duo Gang Starr, he was one of the most influential figures in East Coast hip-hop’s ’90s heyday; as a solo artist, he pioneered jazz/rap fusion with his series of Jazzmatazz collaboration albums. ”I will cherish everything we created together as Gang Starr, forever,” Gang Starr’s DJ Premier said in a statement. ”I’m gonna miss hearing his signature monotone voice when he walks in the room, but the songs will always bring it back to me. His rhyme flows were insane, and I will never remove him from my heart and soul.”… Ron Scalera, a top CBS marketing executive who helped make shows like CSI, NCIS, and The Big Bang Theory hits, passed away April 21 in L.A. at age 49.

Poison’s Bret Michaels in Critical Condition
It’s been a horrific month for Bret Michaels. The 47-year-old Poison singer and reality TV star is in critical condition at an undisclosed hospital after suffering a massive brain hemorrhage. Michaels, who’s currently appearing on The Celebrity Apprentice, was rushed to the hospital on the night of April 22 with a severe headache, and according to an April 26 statement from his management, he remains in an intensive-care unit under 24-hour surveillance while doctors attempt to locate the cause of the bleeding. ”Please remember Bret is, and always has been, a fighter and survivor and is under the best medical care possible,” the statement also noted. The rocker — who has been battling diabetes since childhood — is still recovering from another ailment: On April 11, intense stomach pains forced him to cancel a San Antonio concert at the last minute, and doctors performed an emergency appendectomy later that evening. ”They told me that if I had gone on stage like I wanted to, it likely would have ruptured and I could have died,” Michaels explained in an April 17 blog post. The Rock of Love star has stayed in the headlines this year, duetting with Miley Cyrus on ”Nothing to Lose,” a song from his upcoming album Custom Built, and competing on Apprentice (he was still in contention after last week’s show). For now, that program will be unaffected: The three episodes leading up to the May 23 live season finale have already been shot. — Dan Snierson

More Lindsay Lohan Woes
Lindsay Lohan‘s tough times continue. On April 24, she was fired from indie film The Other Side due to her diminished star power. Producer John Molli told EW in a statement that the film’s backers ”have been resistant to finance the movie with Lindsay in the lead role.” Two days earlier, her father, Michael Lohan, entered her L.A. apartment with sheriff’s deputies to check on the welfare of her sister, Ali, 16, who had been living there. And Lindsay, 23, was reportedly barred from a nightclub recently after throwing a glass at ex Samantha Ronson. Some good news? Her first feature film in two years, Robert Rodriguez’s Machete, is set for release this September. — Adam B. Vary
