I feel fat without spanx: Katy Perry

Los Angeles: Pop star Katy Perry says she is not regular about exercising and feels fat when she is not wearing spanx.

The "Part of Me" singer attended the UNICEF Snowflake Ball in New York City recently, wearing a tight, floor-length, semi-sheer navy Naeem Khan dress with a matching cape. But Perry admitted she didn`t feel as good as others thought she looked. "I feel like my [fat] is sticking out so bad right now. I almost always wear [Spanx], but not tonight, and I feel it pushing out, making me look fat," said Perry. "I like to say I run on the elliptical for 30 minutes watching CNN, but I don`t do it often enough. So I`m just like, `Oh, I guess I`m not fitting into this Lanvin dress for these couple of months`," she added. PTI
