Load Balancer for MySQL MASTER MASTER Replication

We are having typical requirement.

We are having MySQL MASTER-MASTER Replication setup in place. We require to setup Load Balancer between these 2 MySQL servers.

I am aware of setting up WEB based Load Balancer, but we require load balancer for MySQL servers.

Requirement is Application will connect to Load Balancer, Load balancer will connect to DB server by sharing the load.

Please let me know the best approach for this, also let me know if there are any pros and cons.
