Dancing With the Stars' Anna Trebunskaya Pregnant With First Child!

Professional dancer is said to be in her second trimester

This is cause for a celebration, or at least a victory dance!

E! News can confirm that Dancing With the Stars' Anna Trebunskaya is expecting her first child.

A rep for the professional dancer explains that Trebunskaya is approximately four months along and will not be competing on the hit dancing competition show this season.

No word yet on whether she'll return to the ballroom next season. Us Weekly was the first to report of Trebunskaya's future new role as a mother.

The good news keeps coming for the ABC series, on Wednesday the official cast for the upcoming 17th season was unveiled.

And boy, does this look like one you don't want to miss.

Glee fan favorite Amber Riley and former NFL star Keyshawn Johnson are putting on their best dancing shoes, along with Jack Osbourne, Leah Remini and former Jersey Shore star-turned-proud mama Snooki.

Valerie Harper, Bill Nye (the Science Guy), Elizabeth Berkley, a High School Musical star and a Pretty Little Liars hottie will also be competing for the coveted mirrorball trophy come Monday, Sept. 16.

Two other fan favorite pros will be taking a break from the spotlight this season, Maksim Chmerkovskiy and Kym Johnson.

"I wish all the dancers and celebrities in season 17 nothing but love and success, and hope to see you all back on the dance floor for season 18," Johnson said in a statement.
