Peta Murgatroyd is concerned about how she might look when she returns to Dancing With the Stars this spring.

Murgatroyd is set to return as a pro on Dancing With the Stars in March, just a few months after giving birth to her first child, Shai. She and fiancé Maks Chmerkovskiy, who is a fellow Dancing With the Stars pro, welcomed their son on Jan. 4, and now both are set to compete on the dance competition series in the spring.

One of the issues on Murgatroyd's mind, however, is having to deal with her larger breasts brought on by the pregnancy.

"I'm not looking forward to having huge boobs on the show," Murgatroyd admitted to Us Weekly in a new report. "I've never had massive knockers before, and I don't really know how we'll tie them down! I actually contacted the costume designer and said, 'We need to have a meeting about this!'"

Coming back to Dancing With the Stars is also about defending her title. Murgatroyd won last spring's edition of DWTS with model Nyle DiMarco, but had to sit out of the fall season due to her pregnancy. The pro had previously won another season of DWTS with Donald Driver, and now she's looking for her third Mirrorball trophy.

"I want to get my body back," she stated. "And I want to defend my title. I won two seasons ago and never got to come back."

Chmerkovskiy competed in the fall season with model Amber Rose, but did not come anywhere close to the title, finishing in ninth place. Before the fall season he had taken five seasons off after winning season 18 with Olympic ice dancer Meryl Davis. This was his first Mirrorball trophy.

As for who Murgatroyd and Chmerkovskiy will be paired with this season on Dancing With the Stars, all will be revealed on Good Morning America with the official cast announcement.

Dancing With the Stars season 24 premieres Monday, March 20 at 8 p.m. ET/PT on ABC.
