Sarah Jane Nader's pirouetting into the new season of "Dancing with the Stars" just like Brooks did a couple of years ago … but there's one big difference … sources tell us Sarah is paired up with a female pro.
The brunette bombshell was spotted leaving the 'DWTS' dance studio Thursday in a low-cut black athletic top and form-fitting sweats … keeping a low profile with an opaque facial covering obscuring her features, while making sure to show plenty of cleavage.
Other big-name contestants include Jenna Dewan, Tatyana Ali, Tyler Cameron and Jimmy Kimmel's sidekick Guillermo.
Sarah isn't the only person with a family connection to a past contestant either … because Whitney Leavitt's husband — Connor — has also quickstepped his way onto the show while his better half continues to tear it up on Broadway.
Worth noting … Brooks didn't win her season of 'DWTS' — but she did enter into a temporary fling with Gleb Savchenko, which didn't end well for anyone.
While Brooks is over in Europe going topless for the cameras, Sarah is hard at work … and being slightly more modest when it comes to boobs.
We're sure Brooks counseled her sis against entering into a showmance … but blood runs hot in the ballroom.
