Two of the great female voices in Country Music are teaming up to release a duets album.

(AP) - Lorrie Morgan says she and Pam Tillis never know when inspiration will strike.

Morgan says sometimes songs come to her on stage. One of the weirder times inspiration hit her was when she and Tillis were signing autographs. She says Tillis flipped over a photo she was meant to sign and started writing down lyrics.

Most of the time, Morgan writes when she's feeling down. She says her divorce gave her a lot to write about, and when she got over it and felt happier, she had writer's block.

Morgan and Tillis will release a record called "Dos Divas" this summer.
