Who knew that shaking your bon-bon could cause so much controversy?

Deeming it a “betrayal of everything that every Puerto Rican should stand for,” producer-songwriter Robi Draco Rosa criticized on Friday longtime friend and collaborator Ricky Martin for agreeing to perform “La Copa de la Vida (The Cup of Life)” at inaugural festivities for President-elect George W. Bush.

Rosa, who penned “La Copa” as well as Martin’s smash hit “Livin’ La Vida Loca,” says that he sees Martin’s performance, scheduled for Thursday, as an inappropriate endorsement of Bush’s Republican politics.

“This is a very partisan act,” said Rosa, who was in the band Menudo with Martin. “This is a president who would have people in his Cabinet who would obstruct the exercise of civil rights, human rights, consumer rights, the right to choose, the right to be free of gun violence and the right to a clean environment.

Martin has been mum about Rosa’s criticisms thus far.

Other acts scheduled to perform for Bush include Destiny’s Child, ZZ Top and Lyle Lovett. Bush will be sworn in on Jan. 20.

SNOOP VS. DEATH ROW: Another salvo has been fired in the hip-hop war between rap star Snoop Dogg and his ex-label, Death Row Records. The record company has posted a threatening message aimed at Snoop on its official Web site

The label’s head, Marion “Suge” Knight, who is currently serving time for a 1996 parole violation, has repeatedly made no secret of his hatred for Snoop.

The threatening message reads: “2001 the year of fear, All doggs run and hide, Suge is coming home.” After the message, a gunshot is heard, along with the sound of a whimpering dog. Death Row Records and Knight previously posted unauthorized MP3s from Snoop’s latest No Limit album “Tha Last Meal.” Snoop Dogg became a frequent target of Death Row’s anger when he defected from the label for Master P.’s No Limit label.

MAN IN BLACK IS BACK: Johnny Cash, who was previously misdiagnosed with Shy-Drager Syndrome as well as Parkinson’s disease, is actually afflicted with autonomic neuropathy, according to his doctor.

The Web site says that autonomic neuropathy is a grouping of symptoms affecting the central nervous system that includes body temperature fluctuations, blood pressure problems, dizziness, nausea and weight loss.

According to Cash’s doctor, if the singer, 68, really had been stricken with Shy-Drager Syndrome, he wouldn’t have survived as long as he has. Cash has had a number of health-related problems over the years, including alcohol and drug addictions, heart surgery and more than 30 operations for a broken jaw.

Cash recently was nominated for two Grammy Awards for best contemporary folk album and best male country vocal performance for his latest album “American III: Solitary Man.”
