Is Carrie Underwood Joining Skinny-Mini Club?

Did anyone else notice how skinny Carrie Underwood has been getting lately?  I absolutly love her don’t get me wrong, but it seems she’s skinnier everytime I see her.  Last night for her performance on American Idol the first thing I noticed about her when she walked out was her arms.  They are super skinny!  She looks good, but I just hope she stops losing weight.  She’s one of my favorite artists out there right now.  Stay healthy Carrie!
