Are gravitational waves affected by the curvature of spacetime (gravitational lensing)?

Question

I have a basic question I can't seem to find anything on (I keep hearing about how gravitational waves and gravitational lensing were both predicted by Einstein).

We all know about the gravitational lensing effect as it relates to light. Would a gravitational wave also be subject to having its path "bent" around massive objects/following the curvature of spacetime, or would it be able to pass "straight" through? (Or do we know?)

Answer 1

Of course yes, like anything belonging to the universe, but only if the perturbation is not alot smaller than the wavelength, as for any wave meeting an obstacle.

Answer 2

The curvature of spacetime itself is gravity (or acceleration). Gravity should not effect gravitational waves, just as light (EM wave) is not effected by electromagnetism.
