Lemon-Lime Poppy Seed Cake

1 package (18-1/4 ounces) yellow cake mix
1 package (3.4 ounces) instant vanilla pudding mix
1/4 cup poppy seeds
4 eggs
1/2 cup water
1/2 cup vegetable oil
1/4 cup lemon juice
1/4 cup lime juice

Glaze:
1 3/4 cups confectioners' sugar
2 Tablespoons lemon juice
2 Tablespoons lime juice

In a large bowl, combine the first eight ingredients. Beat on low speed for 30 seconds; beat on medium for 2 minutes. Pour into a greased and floured 10 inch fluted tube pan. Bake at 350 degrees for 40-45 minutes or until a toothpick inserted near the center comes out clean. Cool for 10 minutes before removing from pan to a wire rack to cool completely. In a small bowl, combine glaze ingredients until smooth; drizzle over cake.
