Jamie Pressly and Jamie Lynn Spears may have a first name in common - but to hear the My Name Is Earl actress tell it, that's the only thing she's interested in sharing!

The blonde bombshell chatted with the paps as she left Mr. Chow's after lunch (yes, they really do serve more than just dinner!) yesterday afternoon.

Just before she left, though, someone asked for Jamie's opinion about Jamie Lynn Spears' pregnancy - to which the actress snapped back "How 'bout none of my business!"

Yikes!

It's too bad Jamie can't be bothered to talk about Jamie Lynn's condition - after all, she's just a few months removed from her own pregnancy experience!
