(CBS News) In her new memoir, soccer star Hope Solo accuses her "Dancing with the Stars" partner Maksim Chmerkovskiy of being too rough with her during rehearsals.

The Olympian, 31, wrote in "Solo: A Memoir of Hope," that the professional dancer "manhandled" her and once slapped her across the face during her time on the show last fall.

"He manhandled me in rehearsals from the start, pushing me, whacking my stomach, bending my arms roughly. I thought that was just how it went - how dancers worked with each other. I was tough. I could take it," Solo said in the book, according toUSA Today.

"But it kept getting worse," she continued. "One day, Maks was trying to put me in a certain position and hit my stomach so hard with his open palm that I had a red handprint there for the rest of the day."

During a rehearsal for the Halloween-themed episode, she wrote, Chmerkovskiy got so angry with her that he slapped her.

"He wanted my head in a specific position. To achieve that, he slapped me across the face. Hard."

Solo said Chmerkovskiy was "extremely apologetic" after the incident and that ABC offered her a new partner, but she declined. She said she "didn't want to end Maks' career" and feared she'd come off looking like a "prima donna."

Chmerkovskiy's rep had no comment, but the 32-year-old dancer appeared to defend himself against the claims on his Twitter account Thursday:

  • @MacsimC: "Always hated hypocrites and liars...but when someone is both AND an opportunist, I just feel bad for them. Can't win at someone's expense..."

On Friday, he followed up with another message:

  • @MacsimC: "Life's best lessons are the ones that you smile through.....while they hurt you the most! I'm bullet proof....FIRE AWAY!"

On the upcoming "Dancing with the Stars: All-Stars" season, Chmerkovskiy will be paired with his season 12 partner, Kirstie Alley.
