CALABASAS (CBSLA) — Cosmetics retailer Sephora says it will close all its stores across the country Wednesday for diversity training after singer SZA says she was racially profiled at the Calabasas location.

The store closure was announced just over a month after SZA tweeted that a Sephora employee in Calabasas called security to make sure she wasn’t stealing.

“We had a long talk. U have a blessed day Sandy,” SZA’s tweet said.

Sephora tweeted an apology to the singer and said they were taking the complaint seriously.

Hi, SZA. We’re sorry to hear about your experience at our Calabasas store and appreciate you bringing this to our attention. We want to let you know we take complaints like this very seriously and are actively working with our teams to address the situation immediately.
