Sofia Vergara thinks Kim Kardashian should be "upset" that their bums get compared.

The 39-year-old beauty - who plays Gloria Delgado-Pritchett in TV sitcom 'Modern Family' - cannot believe she still features in magazine polls rating the world's most beautiful women because she is approaching 40, and she thinks the 31-year-old reality TV star wouldn't be pleased to be named alongside her.

She exclusively told BANG Showbiz: "It's fantastic to be near the top of the beautiful women polls - I'm nearly 40. I wonder if they're crazy sometimes when people compare my ass with Kim Kardashian's. She's 10 years younger than me, she should be upset! I shouldn't be competing in these lists."

The Columbian beauty still regards herself as "sexy" as she approaches the landmark age - which she will hit in June 2012 - despite admitting she has a "few extra pounds" compared to her fellow famous stunners.

She previously explained: "I have big boobs, I have a voluptuous figure, and I like to laugh a lot, this is who I am.

"But it's great to still be thought of as sexy, especially now that I'm nearly 40. I don't want to look super skinny and I think since I'm nearly 40 now, I'm glad I have a few extra pounds because otherwise your face has more lines."
