GWEN STEFANI still bears a grudge against the boy she shared her first kiss with on a family trip - because he failed to keep in touch.

The COOL singer secretly hopes her one-time boyfriend, Brad, regrets ignoring her letters - now she's a pop superstar.

She says, "I was in the ninth grade, and I kissed this boy - Brad. I didn't even know his last name.

"It was on a family trip to Catalina Island in California. We kissed on the beach, and I remember thinking, 'Oh my God, this is so weird. I can feel his braces!'

"My family left the next day. I wrote to him three times but he never wrote back."
