  We study $\bar qq$-hybrid mixing for the light vector mesons and
  $\bar qq$-glueball mixing for the light scalar mesons in Monte-Carlo based
QCD Laplace sum rules. By calculating the two-point correlation function of a
vector $\bar q\gamma_\mu q$ (scalar $\bar q q$) current and a hybrid (glueball)
current we are able to estimate the mass and the decay constants of the
corresponding mixed "physical state" that couples to both currents. Our results
do not support strong quark/gluonic mixing for either the $1^{--}$ or the
$0^{++}$ states.
