London, Sept 26 : Peter Andre is reportedly upset with ex-wife Katie Price a. k. a. Jordan as she has taken their six-year-old son to cage-fighting classes.

Pals of the 38-year-old singer-songwriter say that Peter was "deeply unhappy" and "very concerned" to learn that Junior was going to mixed martial arts lessons as he is way too young to be taking part in violent pursuits.

"Peter is deeply unhappy and very concerned but is resigned to not being able to do anything about it," The Daily Star quoted a pal of Peter as saying.

According to reports Jordan, 33, who has two other children, Harvey, 9, and Princess Tiaamii, 4, has defended the decision insisting that it was important for the kids to have an active life. (ANI)
