Lookin' good, Jessie James Decker!

Just over two months after giving birth to her and hubby Eric Decker's baby daughter, Vivianne Rose, the 26-year-old country singer stepped out in NYC looking hotter than ever!

Dressed in a pink and green floral dress, tan heels and aviator sunglasses, the sexy star flaunted major cleavage, killer post-pregnancy curves and a tiny waist while walking around and waving to the cameras. To top it all off, the new mother of one flashed a giant smile.
