This Is What Gwen's Abs Look Like???

According to Us Weekly, the flat-tummied look may have been piling on after Gwen pranked fans with an April Fools' Day pregnancy announcement. In NYC on Friday, Gwen Stefani flaunted her incredible figure in an overcoat opened to reveal a black bra and low-slung cargos, with only some sheer fishnet covering her abs. The singer, whose "This Is What the Truth Feels Like" became her first solo album to hit the top of the Billboard charts, was leaving a taping of "The Late Show with Stephen Colbert."
