Kerr, 29, who gave birth to their first child Flynn Christopher with actor-husband Orlando Bloom last year, said her energetic son constantly keeps her on toes and her little boy's latest antics continue to surprise her, reported Us magazine.
"He loves to dance, loves music and he's so smart. The other day we were in South Africa, I turned on the TV and Justin Bieber's documentary was on, 'I said 'Flynn! Bieber' and he said 'Bie-ber.' I said 'Bieber Fever' and he said 'Bieber Fever' (back to me). I thought it was the cutest thing I've ever seen!," she said.
When the Victoria Secret model is away from husband Bloom and their son, Kerr says she keeps her son active with her phone's video calling application.
"When he's away from me, we FaceTime and he says 'Mommy, dancing!' because I'm always dancing with him. He shakes his little booty and claps his hands with the biggest smile on his face."
