The only things that are certain are death, taxes, and TMZ splashing whatever thing you said on the internet. You’d thing movie star and literal dynasty member would know this, but he still decided to spill the X-rated beans to the tabloid when he told TMZ that kissing Jennifer Hudson, which he does in his new movie, Respect, gives him a woody.

Via TMZ:

Marlon Wayans says Jennifer Hudson kisses like she comes from heaven — but he wants to keep it our little secret. And, what he especially wants to keep on the down-low … he gets a woody when he hears her sing.

The actor-comedian broke down what it was like to plant one on his costar on the set of their new movie “Respect” — which is a biopic about the late, great Aretha Franklin.

Last week, Marlon and Jen were seen sharing a smooch while filming, and as passionate as it looked … it was apparently even better in person — for Marlon, anyway. Check out how he intricately describes locking lips with JH … it’s almost too descriptive for comfort.
