Potent putter’s bomb threat brother shame and the HATE between them!

Golfer and skirt-chaser Tiger Woods is furi­ous that his half-brother Earl got busted for phoning in a bomb threat – because Tiger’s afraid it will make HIM look bad!

“Tiger’s all about Tiger,” a close source told The ENQUIRER. “He really doesn’t care about what happens to Earl, but he’s worried that it will hurt his image.

“He said, ‘Why would Earl do something stupid like that? It’s going to make the whole family look like criminals.’

“When it comes to his half siblings, Tiger is as cold as ice.”

Authorities say that burly, bearded Earl Dennison Woods Jr., named after Tiger’s father, allegedly used a cell phone at 8:30 a.m. on Dec. 12 to call in a bomb threat that triggered a terrifying evacuation at his workplace, the Arizona Department of Economic Security in Phoenix.

More than 100 frightened people scrambled out of the facility in fear for their lives. But after 58-year-old Earl turned himself in, he told a reporter: “It was a joke, man. I was joking with co-work­ers.”

Phoenix cops didn’t think it was funny – they charged Earl with one count of misdemeanor use of an electronic device to threaten, terrify or harass. He was released after a brief stay in the Maricopa County Jail, but if convicted he could face up to six months in jail.

Since Tiger’s dad died in 2006, the golf great has had little to do with his two half brothers, Earl Jr. and Kevin, and his half sister, Royce, who were products of Earl Sr.’s first marriage to Barbara Gray.

To make matters worse, said the source, “the family turned their back on Tiger” after The ENQUIRER revealed his affair with New York party girl Rachel Uchitel in 2009, which led to his divorce.

Tiger’s dad, who had called the shots for the family, met his second wife Kultilda Punsawad when he was stationed in Thailand with the Army in 1966. She gave birth to Tiger in 1975.

As he grew, Tiger repeatedly butted horns with Earl Jr., who developed a deep dislike for the superstar. He’s blasted Tiger in the past over his refusal to help brother Kevin, who has multiple sclerosis and is confined to a wheelchair.

“I’d like to slap Tiger, wake him up,” Earl once fumed. “I’d like to say, ‘Don’t come knocking on the door when you need a bone marrow transplant!’ ”
