The eyebrow-raising Live Nation concert with Chris Brown and his Between the Sheets Tour mates Trey Songz and Tyga at Target Center on March 3 has been canceled for reasons not specified, other than the ever-vague "scheduling conflicts." Refunds will be given automatically to fans who bought tickets online or by phone, or they can be had at point of purchase for tickets bought in person.

The start date of the tour was pushed back last month because of Brown's ongoing legal trouble, which stems back to his 2009 assault of then-girlfriend Rihanna before the Grammy Awards. His probation was revoked by a judge last month after it was learned he traveled out of town without permission. One other date on the tour (Bridgeport, Conn., Feb. 20) was also cancelled, while about a dozen other shows had to be rescheduled.

Brown did make it to Sunday night's Grammys in Los Angeles, where he was up for three awards in the R&B categories. His and fellow nominee R. Kelly's presence was noted repeatedly by Twitter critics during and after the segment with President Obama and Katy Perry, who kicked off the new "It's on Us" campaign against domestic violence.
