Beyonce Knowles has been slammed by parents for her risque performance on 'Drunk In Love' at the Grammy Awards.

During her performance, the 32-year-old singer opened her legs on a chair in a G-string before she came undone during an apparent wardrobe malfunction, Metro.co.uk reported.

The 17-time Grammy winner also humped her tush up against her hubby Jay Z after he joined her on stage, which further angered parents.

One of the tweets read that opening Grammy song performance inappropriate for young children, thank you Beyonce with the hashtag `ChannelChange`.
