Robert Irwin ‘Spending A Lot of Time’ With ‘Dancing With the Stars’ Troupe Dancer Hailey Bills

The late Crocodile Hunter’s hunky, grown-up son, Robert Irwin, has gotten super close with sexy pro dancer Hailey Bills after they hit it off on Dancing With the Stars, but insiders say loved ones fear the 21-year-old Aussie’s taking his eyes off the prize and setting himself up for a heartbreaking fall.

Sources say the starry-eyed youngster, who’s been dedicated to the growth of his late dad Steve Irwin’s legacy of the Australia Zoo, has become obsessed with finding love and leaving his close-knit family in the dust.

Says an insider: “Robert’s an innocent kid and was not prepared for this kind of attention and from so many beautiful women.”

“It has his head spinning! He went into this with a really clear focus on using this as a way to bring in money for the family. But now that he’s living this Hollywood life with all these distractions — namely the beautiful women — he’s lost focus a lot.”

Sources share that Robert’s “got a huge crush on Julianne Hough,” but at age 37, the dancing divorcée’s so much older, “it’s not going anywhere.”

On the other hand, DWTS troupe dancer Hailey is right in his age group at 19, so it makes a lot more sense that they should end up canoodling.

“They’ve been spending a ton of time together and the rest of the cast is whispering that they’re an item,” says the insider.

Sources say the handsome wildlife warrior’s also being eyed for big-bucks modeling campaigns and shows like The Bachelor.

“The longer he stays on Dancing, the more money he will make. And his family needs that money to save their zoo.” adds the insider.
