Bride J.Lo's Barbell Blues!

Muscle-bound movie stripper too big for $1.2M gown.

Buffed up J.Lo has gotten too big for her britches — and her $1.2 million wedding gown!

“Jennifer’s bulked up so much, she looks like a bodybuilder!” an insider snitched. “She’s packed on 22 pounds of muscle!”

The bootylicious bombshell bares her bod pole dancing in her new flick, “Hustlers” — and recently announced she’s delaying her wedding planning to film “Marry Me.”
