Terri Irwin has given her son Robert a playful punch on the arm after he made a cheeky comment about his pregnant sister on breakfast television.

Speaking to Channel 7's Sunrise program on Wednesday morning, the famous mother and son duo updated viewers on Bindi's pregnancy.

"She's due next month, so it's that sweet spot where you really miss being able to see your shoes," Terri said.

Robert then added: "She's massive now!"
