(CNN) -- Here are some of the latest tidbits in entertainment news.

Medical examiner's report -- Righteous Brother Bobby Hatfield's sudden death last November, just hours before a concert, was a shock to many. Now comes new word on how it happened. A medical examiner in Kalamazoo, Michigan, reports Hatfield's death was triggered by cocaine. The initial report listed heart failure as a cause of death, but that was before the toxicology tests were completed. The Righteous Brother was 63 years old. He and his partner Bill Medley hit it big with hits such as "You've Lost That Lovin Feeling" and "Unchained Melody."

Fox returns to TV -- Actor Michael J. Fox is making a return to his TV roots. Fox will appear in two upcoming episodes of "Scrubs." He'll play an obsessive-compulsive medic who uses his disorder to his advantage. His "Scrubs" stint will air during the February sweeps on NBC. The guest-starring role reunites Fox with "Spin City" creator Bill Lawrence, who serves as executive producer on "Scrubs."

"Buh, Buh, Bye"-- It's now official. All the rumors and talk of chaos within the popular R&B group B2K were more than just rumor and gossip. They were apparently fact.

With hits such as "Bump, Bump, Bump" and "Uh Huh," B2K gained hordes of young fans, but success obviously doesn't mean happiness. The group's manager released a statement saying the group was disbanding and that the four members are planning to pursue solo careers. The boys have been headlining their own tour. Incidentally, they have a new movie coming out later this month.

Spears' husband of 55 hours, Alexander, said the marriage arose out of a desire to "do something wild, crazy.

Split-ney Spears: Inspired by other brief unions? -- Britney Spear's 55-hour marriage made us rack our brains for other lightning quick celebrity weddings. Of course, naming off all the quickie celebrity unions would take longer than some marriages even lasted.

But a few of note include:

Zsa Zsa Gabor beat out Britney in the time spent from "I Do," to "I want a divorce." Her 1982 marriage to Felipe de Alba lasted one day. But technically she was not married to him because she had not divorced husband No. 7 before walking up the aisle again.

Lisa Marie Presley has bad luck with her marriages so far. Let's forget her strangest one, her union with Michael Jackson. Her shortest one came with actor Nick Cage. The marriage lasted 107 days.

The there was the marriage of Dennis Rodman and Carmen Electra. It was lasted an amazing nine days. Amazing because who would have thought it could last that long?
