Los Angeles, Nov 13:

Singer Britney Spears took a dance class with children aged eight to 18, and taught them how to groove to Pharrell Williams’s hit song “Happy”.

The “Toxic” hitmaker surprised the young dance class in Las Vegas.

She shared some videos of the children practising the dance moves and captioned one of the clips: “My favorite class!”

Spears visited the Vegas dance studio, owned by Fern Adair, in late October.

At that time, the “Womanizer” singer posted on Facebook a photograph in which she was surrounded by students of Fern Adair Conservatory of the Arts.

“Had way too much fun teaching today! Thank you all – you are awesome. #fernadair #lasvegas #danceclass,” she had captioned it. (IANS)
