"My dad doesn't have his speech 100 percent back yet, but the first words he learned were, 'I love you,'" Doherty said on "Good Morning America." "He was crying, and he said, 'I love you and I'm proud of you.'"
After the first two nights of dancing, Pussycat Doll Nicole Scherzinger held the lead with 53 out of 60 possible points.
Scherzinger and partner Derek Hough earned the first 10s of the season from judges Carrie Ann Inaba and Bruno Tonioli for their jive. Tonioli called her performance "phenomenal."
"I have never seen a jive that good the second week," he said. Watch "Dancing With the Stars" Monday at 8 p.m. ET on ABC.
