Karolina Kurkova Talks About Pregnancy and Son's Excitement About Becoming a Big Brother--Watch!

Karolina Kurkova, who is expecting her second child, says her and husband Archie Drury's 5-year-old son Tobin is "super excited" about becoming an older brother.

The 31-year-old Czech supermodel made her comments exclusively to E! News on Thursday at the House of Gant Presentation during Spring 2016 New York Fashion Week.

"He is very ready," she said about Tobin. "He is super excited to be an older brother. Real excited, kisses my belly."

She said he tells her, "'Mommy you have to sit, you have to like rest.'

"You know, 'You need candy,' so I can have candy,'" she added.

Kurkova told E! News her pregnancy has been going "really good" and that she is preparing for her third trimester, a time of "resting, "eating" and "cleaning out," after traveling with her family.

Meanwhile, Kurkova is keeping busy--after a high fashion-filled day, she spent much of Friday volunteering to bag fruit with workers at City Harvest's food rescue facility in Long Island City, New York for Feeding America and Hunger Action Month.

The supermodel announced her pregnancy in July and later revealed in a Facebook selfie video that she was having another boy.

"Hi, this is Karolina and I'm here to announce the sex of my second baby," she said. "So those of you who guessed that he's a boy are correct."

The supermodel had encouraged her social media fans to guess the sex of her second child.

"Guess the sex of my second bundle of joy!" she said in July in an Instagram post, which contained a photo of her son Tobin holding up a strip of ultrasound pics. "Like this post to vote for a girl and leave a comment to vote for a boy. I'll randomly pick one person who guessed correctly and make you a personalized shout out video from me! :) Good luck! #KKBaby2."

In her Facebook video, she said she picked the name of a person who guessed correctly out of a hat. The winner was a woman from England, who is also a mother.
