Selena Gomez Can't Stop Smiling on St. Patrick's Day

On Friday, Selena stepped out and showcased her new look while riding a bike in Los Angeles with a girlfriend. The "Come and Get It" singer rode around in jeans, a white t-shirt and blue cardigan. Of course, her smile during the fun-filled activity with her gal pal was just a bonus.

She was photographed sporting her new hairstyle on Thursday, while wearing a pink tube top, jeans and a long, tan cardigan.
