Brooklyn Decker's said bye-bye to her blonde locks!

The Sports Illustrated Swimsuit model dyed her hair a light brown yesterday ... and debuted her new look on the red carpet last night.

The 25-year-old wife of Andy Roddick rocked her brunette tresses at the God's Love We Deliver 2012 Golden Heart Awards Celebration on Monday in New York City.

It's definitely a darker 'do for the beach blonde, who seems to be embracing the season change with her hair color.
