Kelly Clarkson ridiculed over her weight gain live on air

Our hearts go out to Kelly Clarkson this weekend after she was slammed on American radio programme The Mike Gallagher Show for having gained weight in recent years.

Host Mike Gallagher was enjoying an informal chat with FOX News journalist Chris Wallace when things took a turn for the seriously spiteful.

Shooting the breeze about their favourite pizza toppings, Mike suddenly decided to bring the Because of You singer into question.

Seemingly out of nowhere, 54-year-old Mike suddenly said: "Have you seen Kelly Clarkson? You know the singer, Kelly Clarkson? Holy cow, did she blow up."

Initially reluctant to engage in the body-shaming conversation, FOX star Chris called Mike out on his cruel remarks, but it wasn't long before he decided to join in.

In what sounded like playground bullying, 67-year-old Chris said: "She could stay off the deep dish pizza for a while."

Referring to the fact that Kelly had only recently become a mum, the two men decided that couldn't account for Kelly's shape and continued to slam the star for her appearance.

Kelly has admitted in the past that she refuses to allow people's cruel jibes to get to her and we hope she continues to maintain that healthy attitude.
