Report: LeAnn Rimes Had A Boob Job

Did the country cutie pull a Kate Hudson?

LeAnn Rimes, 28, showed off a fuller upper body while strolling around in a bikini in Cabo San Lucas last week with fiance Eddie Cibrian, and it's because she "got a boob job," reports Us.

Their source goes on: "She’s always, always been insecure about her size. She was a small A-cup. She often talked about wanting to get implants. She’d say, 'I just want a little bit so they’re proportionate to my body.'"

And who did LeAnn allegedly go to for the procedure? Brandi Glanville's plastic surgeon! And she apparently got the same cup size...

"When Brandi and LeAnn were constantly fighting, one of LeAnn's jabs at Brandi was that she was plastic. Brandi replied, 'Be careful, honey. That's what Eddie likes. You'll be there someday too.' Looks like Brandi was right!" says the insider.

So whaddya think - is the rumor true?
