Well Carrie Underwood sure did wow 'em at the Grammys last Sunday night. Her number one hit single "Blown Away" scored trophies for Best Country Solo Performance and Best Country Song (which was awarded to songwriters, Josh Kear & Chris Tompkins). She performed an over-the-top medley of "Blown Away" and "Two Black Cadillacs" complete with an amazing technicolor video ball gown. And she showed up for the festivities at the Staples Center rockin' a $31 million Jonathan Arndt diamond necklace. Serious bling. But, walking around in public with that kind of super expensive sparkle made the superstar a little nervous. “It’s heavy on my soul,” she admitted to E! News. “I’m afraid someone is going to tackle me and steal it … It’s worth more than me.”
