Gemma Collins looks slimmer than ever as she dances in workout gear during the heatwave

GEMMA Collins turned up the heat as she danced in her huge garden during the sizzling sunshine.

The TV star worked up a sweat after being challenged to "jump and jive" on Instagram.

Looking slimmer than ever after her recent weight loss, she invited fans to join in telling them: "Jane Fonda's got nothing on me!"

Gemma got jiggy to Meghan Trainor's hit All About That Bass and looked radiant as she plugged a bingo brand at her mansion.

The Diva Forever personality gushed: "Huns welcome to Day 2 of my Bingo Blitz. Challeng to jump and jive, jazzercise."

Recently, Gemma teased the secret behind her 3.5 stone weight loss: a delicious chicken, salad and rice dish.

It has been reported that Gemma has since gone on to lose a total of five stone in the past four years.

Gemma started losing weight while training for Dancing On Ice.

She recently revealed a further secret to her weight loss - fat busting sessions in a cryotherapy chamber.

Gemma said she had shifted the pounds by brief exposure to temperatures close to -200C.

However, she enjoyed the warmth of the current heatwave yesterday when she could be seen strolling around the grounds of her stunning Essex mansion in a bikini.

Gemma flashed her stomach after confessing she had shed three and a half stone.

She posed for an Instagram video in which she told fans her swim attire was from her collection with high street retailer New Look.

The Diva Forever personality gushed: "It is absolutely amazing for the sun and basically it is going to be a great day."
