Solange Knowles, younger sister of Beyonce, has her own thriving music career. Maybe too thriving? Solange announced on her website that she was canceling some upcoming tour dates, for family reasons.

As she wrote, "I am completely devastated to announce that I will be canceling my international festival dates for the summer. I wish I could put in words how much of a difficult decision this was…but between moving part time to a new city, starting my son in a new school, and writing/recording my new record…I really had to make the best decision for my mental/physical health and provide some stability for my family.  I am so so sooooo sorry if I’ve disappointed… and really hope to make it out to those special cities soon enough!"

According to People, Solange, 27, was supposed to tour for about two weeks, visiting nine cities in Europe. Her son, Daniel Julez, is 8, and they recently relocated from Los Angeles to Brooklyn. She's reportedly divorced from Daniel Smith, whom she married when she was 17.

It sounds like Solange's August U.S. tour dates in L.A. and Philadelphia are still on, for now. It probably isn't as hard for her to travel there, and you have to pick your battles as a working mom. Good luck to her!
