Crashes while loading multiplayer or when clicking on single player world

Every time I open up Minecraft, it will load up to the menu screen. If i click on Multiplayer, it will freeze, and crash. If I click on Single Player, it will take me to my saved worlds. When I click on a saved world, it will freeze and crash as well. Whats going on? I have included the most recent crash report I have recieved below.
