Saints Row 3 "Love is What I got" has no facial animations...

[darkely]

In Saints Row 3 when you go on a certain mission you and Perice start
singing "Love is What I Got". My issue with it is why the hell are there
no face animations?! I look in the car to see if they sing but all they
do is just sit with a blank face.

The thing is though in all of the rest of the game (in car, cut scene, or on foot) the players mouths are animated whenever they talk. My game is updated but still no animations... So is this laziness on the devs. part
or what?
