Solange had a banner breakout year, debuting on late-night TV, playing music festivals, from SXSW to Coachella, and touring across the world with her new EP, True, and its sexy-groovy single "Losing You." But apparently the buzz mill is taking its toll on Beyonce's stylish lil sis. Solange just scrapped her European tour, citing mental and physical health.

She made the announcement via a letter to fans on the website for Pukklepop, a major festival in Belgium where she was scheduled to perform.

"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!"

While True was released via Grizzly Bear member Chris Taylor's independent label Terrible Records, Solange recently teamed with Columbia, her sister's label home, to launch her own label called Saint Records, which will be distributed through Columbia's parent company, Sony. Saint Records is "where I'll be releasing my full length album, and also future music projects that I'm excited about sharing!" Solange tweeted this spring.
