Cheesy Bratwurst Soup

My Mom gave me this recipe, and it's really delicious on a cold winter night! You can take the skin off your potatoes if you prefer, I just left mine on.

1 package of bratwurst, browned and cut into 1/2 inch slices
4 medium potatoes, cubed
1 small onion, diced
1/2 cup celery
1 can of corn, drained
1 cup cheddar cheese
8 oz of Velveeta block cheese
1 (10.75 ounce) can of cream of mushroom soup
1 (10.75 ounce) cheddar cheese soup
2/3 cup beer

Place all the ingredients in a slow cooker. Cover, and cook on medium to high for 3 hours, or until potatoes are tender.
