Bindi Irwin’s Secret Shame!

Bindi Irwin

Bindi Irwin waltzed her way into America’s heart on “Dancing With the Stars” — but she’s lost that lovin’ feelin’ for some of her own family members!

After Bindi won the show’s coveted Mirrorball Trophy on Nov. 24, The National ENQUIRER learned the 17-year-old daughter of late “Crocodile Hunter” Steve Irwin is on the outs with a cousin, along with her grandfather!

William Wilgus, a relative on her mother Terri Irwin’s side, was busted for misdemeanor assault in 2008 and sentenced to road crew work in Eugene, Ore.

He completed his seven-day sentence in 2009, official records show.

“It’s a black cloud hanging over Bindi,” a source revealed. “Bindi broke down in tears when she won the show competition, and paid homage to the memory of her dad, but she was hiding a lot of shame within her family.”

Bindi hasn’t spoken to her grandfather, Bob Irwin, for years. The ugly feud erupted after Steve was killed when a stingray barb pierced his heart in September 2006.

Steve’s widow, Terri, and Bob clashed over how to continue to run the family business, the Australia Zoo, which Bob founded.

In 2008, Bob quit amid rumors that Terri had him banned from the property.

“Bindi and her younger brother, Robert, haven’t spoken to their grandfather in years,” said the source. “You have to give her credit for accomplishing what she did on ‘Dancing With the Stars’ after all the turmoil she’s been through with her family.”
