Avril Lavigne probably is pregnant as we mentioned yesterday, because now TMZ is reporting that she plans to marry her fiance, Sum 41 frontman Deryck Whibley this summer.

She also is said to wants kids right away, which is celebrity-code for “I’m pregnant.”

A more mature blonde-haired and groomed Lavigne appeared at the Kids Choice Awards last week looking nothing like she did during her ‘Complicated’ years. And speaking of kids, Avril wants some of her own, and stat.

Lavigne — who got engaged to her fellow Canadian last summer — has told her friends to brace themselves for a traditional white wedding at an undisclosed church in Beverly Hills.

Avril is said to be planning a reception with circus performers, comedians and popular rock bands. She’ll probably make a mint off selling the pictures.
