Robert Irwin is quickly becoming a sex symbol … and now he’s been offered a guest spot to show off his rockin’ bod at the famed Chippendales.

Here’s the deal … the Australian wildlife conservationist — and son of the legendary Steve Irwin — has been killing it on “Dancing with the Stars” … but a recent shirtless moment really sent fans over the edge.

His chiseled chest also caught the attention of the bosses over at Chippendales in Las Vegas … and TMZ has learned they sent a pitch to his manager — who happens to be his mother, Terri Irwin — asking if Robert wants to come dance in Sin City once the network show is done.

According to the pitch obtained by TMZ … Robert would be a perfect celebrity guest host … joining the likes of Tyson Beckford, Vinny G. and Joey Lawrence, all ‘DWTS’ alums who’ve danced at Chippendales after their time on the program.

The pitch concludes … “His personality, kindness, skills (and body!) make for a perfect celebrity host!”

It’s worth noting … his ‘DWTS’ pro partner Witney Carson expressed regret after the shirtless moment … since she’s the one who ripped off his shirt and opened the floodgates of drool, a distraction from their ultimate goal — winning the whole damn thing!
