The England international has claimed that he has given the prolific winger "stick" for naming his baby girl Alba Violet Bale, who was born in October.
"Gaz has little AVB and is buzzing," the Daily Mail quotes Defoe as saying. "I give him stick about her initials. He is the first to give someone banter. So when you have a chance to give it back, you take it."
Defoe became a father to son Joshua-James last month.
