READ: Singer receives love from Sam Smith

After her post with the caption, 'Bored', a put down from a fan was definitely the last thing Brandy needed.

The fan had commented on the video, comparing her play to that of his 9-year-old nephew:

"Really??? why post bullshit like this? my 9 year old nephew can play the keys better than this."

Brandy was quick to clap back, saying:

"Luky, i will sing you and your nephew under any and every table you own! I'm blocking you now so it's no need to respond."
