Strictly Come Dancing professional Kevin Clifton, 36, will appear on ITV show This Morning alongside his sister and fellow dancer Joanne Clifton, 35.
Ahead of their appearance, he shared three pictures of the siblings, including the separate times they won Strictly.
Kevin won the BBC Show with his now rumoured girlfriend Stacey Dooley, 32, last year, while Joanne and Ore Oduba, 33, lifted the Glitterball trophy in 2016.
He also shared a throwback snap of him and Joanne as children looking excited as they showcased their trophies.
Many of his fans flocked to his page to speculate what the announcement could be.
One user wrote: “Your going on tour together or one of you is the new strictly judge.”
A second penned: “Not leaving Strictly, I hope???”
A third commented: “Can’t wait to hear it. You and Joanne were so cute when you we’re little x.”
Kevin’s impending announcement comes after Stacey Dooley spoke out about having a smear test.
The dancer’s rumoured girlfriend filmed herself leaving a doctor’s surgery on Instagram.
“From showing off in the south of France to lying in docs bed with my f***y out,” she captioned the video.
She then said: “Gang, I have just come out from having my smear test. [It] didn’t hurt, didn’t take long.
“Got myself in a tizz,” Stacey admitted. “She was an angel.”
Stacey went on to urge her 726,000 Instagram followers to stay on top of their smear tests.
