In "The Perfect Brother" (season 1), Jane refers to Alan's "parents" in the plural.

In "Kids are from Earth, Parents are from Pluto" (season 5), Brain calls his parents "mom" and "dad" individually.

And there are other references to her as "Brain's mother", but I can't think of a time when it was said that his parents were married. Actually, a lot of the parents on the show are like that.
