Are Steel Magnolia breaking up ?

I heard that the country band Steel Magnolia are breaking up. I hope it’s not true because my 5 years old niece loves them. She hasn’t got to see them yet. They’re her heroes and she really wants to see them and meet them. She has posters of them in her room and she has they’re whole album on her iPod and she knows all the words to their songs. She talks about them all the time and she makes up stories about them and she says she wants to marry the male singer. Are they really breaking up or is it just a rumor ?
