The Blues midfielder scored the matchwinning goal against his former club on Saturday but his goal celebrations were far from exuberant because of, he explained, his ties with the Hammers.
"I supported West Ham as a boy and I'll always support West Ham," he has said.
"That is my home club. I was fortunate enough to play for them. I respect the club and people involved, Zola, Clarke and obviously the fans."
Bowyer has been in excellent form this season, chippng-in with six goals from midfield that has helped Blues gradually move up to the dizzy heights of eighth in the Premier League table and he has put his good form down to feeling appreciated by management, team-mates and fans at St Andrews.
"Everyone wants to feel loved in a way, wanted, and that is how I feel here," he added.
"The management, coaching staff and the fans have made me feel like that.
"I wasn't down at West Ham. It was just I didn't think I got a fair go once Curbishley went. That is out of my hands.
"When you feel you should be playing in front of other players, you are not in control. I didn't think I had a fair go but that is football.
"Football is about opinions and decisions and that is why I am here now and I'm proving people wrong."
