SEOUL - A member of popular South Korean girl group Red Velvet, Wendy, has been criticised for her impression of how she thinks African-Americans speak, reported Allkpop.com and popcrush.com.

The 24-year-old, who grew up in Canada and the United States, had been asked on South Korean talk show Talk Mon to discuss the different ways that English is spoken in the US.

In the episode that aired on television on Monday (March 5), she was seen delivering an impression of how she thinks white girls speak, going into stereotypical valley-girl mode. She then imitated how she thinks black girls speak, giving an impression of an exaggerated, stereotyped sassy girl, complete with wagging fingers and pursed lips.

International viewers of the show immediately took offence and went on social media to chastise her for being racially insensitive.

Twitter user @alderbluee wrote: "I'm not going to stand for wendy bc what she did was totally wrong. Wendy is a grown women and she should be careful with her actions, this is the second time she do this and i can understand why you are mad but that doesn't give you the right talk to s**t about her or red velvet."

User @delgado709 tweeted: "I'm so disappointed in Wendy... the imitation she did here is incredibly discriminatory and disrespectful. She's coming from a group that excels in R&B... and you'd think she'd know better... Wendy needs to know what she did was wrong and needs to be educated on that matter."
