Why are my calla lilies bending?

Hi I was given potted calla lilies in April and now some of the flowers are bending at the stem towards the ground. Why is this happening and what should I do?

When calla lilies are pollinated, the seed stalk becomes heavy and bends over to the ground. To prevent them from self seeding you can cut off the developing seed stalk.
