4 spoilage by PureDWTS. Per the report, 21-year old actress and singer Sasha Pieterse, who portrayed Alison DiLaurentis on "PLL," will don her dancing shoes and go for glory alongside pro Gleb Savchenko.

Savchenko, who recently welcomed his second daughter with wife Elena Samodanova, most recently competed with "Real Housewives of Beverly Hills" star Erika Jayne, but made his biggest "DWTS" splash with country singer Jana Kramer during their barely-safe-for-primetime shower dance during season 23.

Other alleged 'Dancing with the Stars' 2017 pairs

Just a single pair --"Property Brothers" star Drew Scott and reigning "DWTS" champion Emma Slater, who won the title this past spring with NFL star Rashad Jennings -- has been formally confirmed by producers. The rest of the rumored pairings include the following:

  • 98 Degrees star Nick Lachey and Peta Murgatroyd
  • TV personality Vanessa Minnillo Lachey and Maksim Chmerkovskiy
  • "Malcolm in the Middle" alum Frankie Muniz and Witney Carson
  • ESPN personality and former paralympic swimmer Victoria Arlen and Valentin Chmerkovskiy
  • "Hamilton" star Jordan Fisher and Lindsay Arnold
  • Violinist Lindsey Stirling and Mark Ballas
  • NBA star Derek Fisher and Sharna Burgess

Only two professional dancers' celebrity partners remain a mystery.

Alan Bersten, who will debut as a pro coach this season, teased that his partner likes the color pink. Cheryl Burke -- who returns to "Dancing with the Stars" after a single-season absence -- was allegedly originally paired up with Bobby Brown, who opted out of the show at the last minute. Producers did, however, find a replacement, and according to Pure, Burke's new partner is "an improvement" over Brown.
