The aim of this paper is to prove existence and regularity of solutions for the following nonlinear singular parabolic problem
$ \left\{ \begin{array}{lll} \dfrac{\partial u}{\partial t}-\mbox{div}\left( \dfrac{a(x,t,u,\nabla u)}{(1+|u|)^{\theta(p-1)}}\right) +g(x,t,u) = \dfrac{f}{u^{\gamma}} &\mbox{in}&\,\, Q,\\ u(x,0) = 0 &\mbox{on} & \Omega,\\ u = 0 &\mbox{on} &\,\, \Gamma. \end{array} \right. $
Here
$ \Omega $
 is a bounded open subset of
$ I\!\!R^{N} (N>p\geq 2), T>0 $
 and
$ f $
 is a non-negative function that belong to some Lebesgue space,
$ f\in L^{m}(Q) $
,
$ Q = \Omega \times(0,T) $
,
$ \Gamma = \partial\Omega\times(0,T) $
,
$ g(x,t,u) = |u|^{s-1}u $
,
$ s\geq 1, $
$ 0\leq\theta< 1 $
 and
$ 0<\gamma<1. $
Keywords: Singular parabolic problems, degenerate coercivity, existence, regularity, lower order term.
