"Everything is great [with Lina's pregnancy]," Dovolani told People.
Dovolani isn't a stranger to parenting, as he and Lina already have 2-year-old daughter Luana.
"Kids are a blessing and give your life purpose," he told People.
Winokur -- who is married to King of the Hill writer Judah Miller -- was diagnosed with cervical caner seven years ago and needed a hysterectomy. While she made a full recovery, Winokur said the cancer scare meant motherhood would most likely be out of the question.
However thanks to a surrogate mother, Winokur is now expecting a son -- meaning both she and Dovolani have happy feet regardless of how they do on Dancing with the Stars.
"I cannot stop smiling this year and part of the reason is Marissa is a sweetheart," Dovolani told People. "I'm thinking about my babies and she's thinking about her baby. Now if somebody doesn't point their toe it's no longer as important as it used to be."
