Maximally extending the Higgs sector of the Glashow-Salam-Weinberg model by including all scalar and pseudoscalar J=0 states expected for 2 generations of quarks, I demonstrate that the Cabibbo angle is given by tan^2(theta_c) = (1/m_K^2-1/m_D^2)/(1/m_\pi^2-1/m_{D_s}^2) \approx (m_\pi^2 /m_K^2)(1-m_K^2/m_D^2 + m_\pi^2/m_{D_s}^2).
