Given the high marks from judges that Melissa Rycroft and partner Tony Dovolani have received on Dancing with the Stars’ all-star season, it’s hard to tell that the reality star is having trouble getting her moves down.
But Rycroft, 29, admits that since giving birth to daughter Ava Grace last year, her body isn’t as mobile as it was during her first time competing on ABC’s hit show.
“I think Tony and I noticed right off the bat that my body is very different than it was,” she recently told PEOPLE during rehearsal.
