The R&B artist said she had been racially profiled while shopping at a Sephora store in California.

The firm told Reuters it was aware of the incident but said the training was not "a response to any one event".

Last year Starbucks held inclusion training amid racial profiling allegations.

In a tweet on 1 May, SZA said while shopping at a Sephora store outside of Los Angeles, an employee she identified as "Sandy" had "called security to make sure I wasn't stealing".

The company responded at the time on Twitter: "You are a part of the Sephora family, and we are committed to ensuring every member of our community feels welcome and included at our stores."

Last year US website Refinery29 reported the singer had previously worked at Sephora.

SZA has been nominated for numerous Grammy awards, and recently collaborated with Kendrick Lamar on the track "All the Stars" which featured on the soundtrack of the film Black Panther.

In a Facebook post, Sephora said it would hold "inclusion workshops" on the morning on 5 June at its US stores as well as its distribution centres and corporate offices.

Sephora did not immediately respond to BBC requests for comment about the training.

Emily Shapiro, a spokesperson for Sephora, told Reuters the store closures were not "a response to any one event," saying that planning for the "inclusivity workshops" had been in progress for months.

The move came after the firm had to apologise over the arrest of two black men who were waiting to meet someone in a Starbucks in Philadelphia in May 2018.

The incident sparked calls for a boycott of the coffee chain.
