Pregnancy looks good on Carrie Underwood in a newly-released preview clip of her video for 'Something in the Water.' The superstar will debut the song live on the 2014 CMA Awards broadcast, which she is co-hosting for the seventh consecutive year with Brad Paisley.

Underwood shared the video preview above with 'Entertainment Tonight.' The singer sports a growing baby bump in the clip, which also features a troupe of 12 dancers, 16 choir members, three costume changes and a custom-built tank of recycled water under the direction of Raj Kapoor, who also directed Underwood's Play On and Blown Away tours.

'Something in the Water' is the lead single from Underwood's upcoming 'Greatest Hits: Decade #1' album, which is set for release on Dec. 9. The album includes a cross section of Underwood's biggest hits, two new studio tracks and four songs in never-before-released versions. It is currently available for pre-order at iTunes. Fans who pre-order will be able to use the "Complete My Album" feature to avoid downloading tracks they've already ordered in the past, resulting in a lower list price and no repeat tracks. The album download also includes the video for 'Something in the Water.'
