Duane Chapman, more popularly known as Dog The Bounty Hunter, is "shocked and heartbroken" over the alleged abuse his nine-year-old grandson, Travis Jr. suffered at the hands of his father, Travis Mimms Sr.

As RadarOnline.com previously reported, Chapman won custody of Travis Jr. after a shocking audiotape surfaced allegedly documenting a severe beating of the child by his own father.

The A & E reality star released a statement Monday detailing his feelings over the shocking incident, and begging Travis Sr. to seek help for his anger issues.

Duane “Dog” Chapman and wife Beth love a good chase and now they’re after Randy Quaid, RadarOnline.com has exclusively learned.

Quaid fled the United States with his wife Evi after the two were facing charges for damaging a home they once owned and failing to pay hotel bills and the bizarre couple made a new home in Canada, where Evi has citizenship.

Beth reached out to Randy on Thursday via an open letter on her website in which she rails him for sucking “other unsuspecting folks into your drama” and promises “we’re gonna get ya no matter where you go no matter how long it takes.”

“As my husband, Dog the Bounty Hunter, was crossing the border into Canada today, it crossed my mind how scared you must be!” Beth wrote.

A colorful collection of Hollywood characters appeared on the red carpet for the Comedy Central Roast of Charlie Sheen on Saturday, and RadarOnline.com was there to capture the action.

Surprisingly, the man of the moment was remarkably relaxed, a startling contrast to the tiger blood spewing crazy man who ranted on a webcam earlier this year.

Porn star Ron Jeremy revealed how he owed his mainstream movie career to Sheen.  "He’s a friend and he’s a really good guy and I like him. He’s a fan of porn stars, he just likes people who have that kind of attitude."
