"Dancing With the Stars" professional dancer Derek Hough recently showed off his toned abs amid rumors that he's dating his former partner Bindi Irwin.

On his Instagram account, the 30-year-old reality TV star shared a photo of himself looking firm as ever.

"Best cure for 3 flights and almost 20 hours of flying is getting straight back into it, Motion=Emotion. #motionequalsmotion #rageagainstthemachine," he wrote.

Fans of Hough couldn't help but tease him for posting such a snap. Some of them believe that he did so to show the rest of the world that he isn't threatened by Irwin's boyfriend Powell.

Meanwhile, there have been rumors that Irwin and Hough are already dating. However, the 17-year-old Australian national never shied away from telling media outlets and publications that she's still very much in a relationship and in love with Powell.

Just recently, Irwin shared an adorable video with Powell via her official Instagram account. In the video, Powell and Irwin told fans that they were going hiking. However, the hilarious tandem ended up laughing when they seemed to not be able to get their facts straight.

"Pretty much sums up our relationship... Thank you @chandlerpowell for always making me smile," she wrote.

In other news, Irwin recently spoke with Women's Weekly Magazine about her anxieties from her father Steve Irwin's death in 20016. On her Instagram account, Irwin thanked the publication for giving her the chance to share her story to the rest of the world.

"Blessed to be given a beautiful opportunity to share my story in this holiday season's edition of @womensweeklymag," she wrote.

One fan of Irwin couldn't help but say how beautiful the young girl is inside and out.

"Bindi, you look so beautiful; the picture is stunning... Hope you et your famille/loved ones are STILL having a lovely Christmas," the fan wrote.
