Working moms everywhere are likely to understand the difficult decision Solange Knowles
just had to make.
The singer says she is "devastated" to announce that she has cancelled her European tour dates for August 2013.
"I wish I could put in words how much of a difficult decision this was," the singer, 27, writes on her web site
, "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."
Knowles just relocated from Los Angeles to Brooklyn, N.Y., and her son Daniel Julez is 8 years old. The star would have been touring for about two weeks and visiting nine cities, including Oslo, Copenhagen and London.
"I am so so sooooo sorry if I've disappointed ... and really hope to make it out to those special cities soon enough!" she said.
There is no indication that Knowles will cancel her domestic tour dates in Los Angeles on Aug. 24 and Philadelphia on Aug. 31.
