Eddie Murphy girl is having his 10th kids

Eddie Murphy is about to have enough kids to play a regulation basketball game at family gatherings — his gf is pregnant with his TENTH child!

Paige Butcher was showing off her baby bump Monday in L.A., and looking pretty damn hot while doing it. The form-fitting pink dress and jean jacket scream MILF alert … even in casual flip-flops. 

Eddie and the Australian actress are expecting their 2nd kid together in December … but the little one will put Ed in double digits overall.
