She and Mark Dacascos was one of the most enjoyable couples last season on Dancing with the Stars, so it's really too bad when fan favorite and So You Can Think You Can Dance grad Lacey Schwimmer announced via Twitter that she won't be part of this season's batch of professional dancers.

"Hey twitterbugs! I will not be doing DWTS this season. But be sure to tune in! <3," wrote the 21-year-old Schwimmer, who also partnered with Lance Bass and Steve-O.

Some thirty minutes later, Schwimmer added that she was also "sad" to not be part of the show's tenth season, what could have been her fourth since 2008. No reason was given for the non-return.

Another pro, Jonathan Roberts, announced - also via Twitter - that he will not be waltzing on the Dancing center stage this season. The former partner of Mary Osmond in season and Macy Gray last season, however, doesn't rule out the possibility of performing in results-night numbers, assuming they don't cut those.

As for who are actually participating, both Cheryl Burke and Derek Hough confirmed that they'll be on the show's tenth run.

"For everyone wondering if I'm doing Dancing with the Stars this season I'm...I'm Not not doing season 10...," wrote Hough, who last season made a splash partnering with model Joanna Krupa.

Karina Smirnoff has previously confirmed that she'll also be making a return, post-Aaron Carter, prompting rumors that former/estranged flame Maksim Chmerkovskiy is thinking twice of joining.

"All the feathers and sequins in the world wouldn't be able to cover the bad feeling between those two", a source previously described their tiff on the set of Burn the Floor in Broadway.

Other stars who have confirmed a reprisal of their roles are Louis Van Amstel, Chelsie Hightower, and Mark Ballas. Newcomer Damian Whitehood from the Broadway dance revue Burn The Floor is also set to make his DWTS debut.
