The 36-year-old cage fighter and reality television star, who is engaged to 28-year-old Chantelle Houghton, said that he will do all he can to protect his child as she grows up.
Reid told Now: "She'll be a bad-ass. I'm already planning on taking her to jujitsu. I'm not going to let any boys mess her around.
"I'm going to train her hard. Make her really strong in the mind, so she knows what's right and wrong and how to handle tricky situations. I feel that's my role."
When Houghton revealed the gender of their unborn baby, she said: "It was such a shock. I just sat there crying and Alex was completely open-mouthed. It all became so much more real." She also warned Victoria Beckham that daughter Harper Seven will have some "serious competition" in the fashion stakes.
Reid recently said of becoming a father: "We're gonna be the best [parents]. I really can't wait to be a daddy."
