Solange Knowles needs a time out. Citing her "mental/physical health," the "Losing You" singer -- and younger sister to Beyonce -- has canceled a slew of European music festival concert dates in order to regroup at home with her 8-year-old son, Julez, and work on a new album.

"I am completely devastated to announce that I will be canceling my international festival dates for the summer," the rising star, 27, said in a statement. "I wish I could put in words how much of a difficult decision this was." Knowles, whose late 2012 EP True garnered huge critical acclaim, admitted that she's feeling overwhelmed of late.

"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," said the star, who recently moved (part-time) from Los Angeles to NYC with Julez, whom she shares with ex-husband Daniel Smith. She added that she wants to "provide some stability for my family," she continued.

She added apologetically: "I am so so sooooo sorry if I've disappointed and really hope to make it out to those special cities soon enough!"

Solange -- whose sister Beyonce is currently on her Mrs. Carter World Tour -- is reportedly dating music video director Alan Ferguson.
