Howard K. Stern Doesn't Lack Appeal

Howard K. Stern has filed an appeal in his ongoing paternity battle over Anna Nicole Smith's daughter, Dannielynn, this according to "Entertainment Tonight."

TMZ is told that the appeal will absolutely delay the reveal of DNA results, but for how long is unknown. The next hearing is April 3.

Last week, Stern followed court orders and drove Dannielynn to a lab for a DNA swab. Larry Birkhead also gave a sample.
