Jacqui, 57, is partnered with pro Anton du Beke, and despite looking like she was having fun on Saturday, faces the possibility of elimination this weekend.
Bookies have hedged their bets that Jacqui will be given the boot after she came bottom of the leaderboard with just 13 points.
Just ahead of them are Jamie Laing and Karen Hauer, while sitting pretty at the top are HRVY with Janette Manrara, and Maisie Smith and Gorka Marquez in second.
But Jacqui’s not giving up easily, putting in the hours to give it her best shot – and hopefully avoid axing.
“There has been quite a lot of bouncing,” she told today’s Good Morning Britain, “My knees are suffering and my feet are in agony.
“I’m getting through the plasters like a rate of knots, but I’m really enjoying this dance.
“All I need to do – all I need to do – is give it some welly and hopefully make sure everyone enjoys it as much as I am.”
Saturday saw Jacqui and Anton receive some pretty brutal feedback from the judges, not least from resident hard-nut Craig Revel-Horwood.
“For me, it lacked musicality,” he said bluntly, “which made it end up a little bit lumpy. You need to double your energy, darling.
“It all got very House of Commons when you went over to get your cane and top hat. You can’t just give up and stop dancing while you get the prop – you need to dance your way there.
“Make sure you close your feet there when they’re meant to be closed, you could drive a semi trailer through them throughout that!”
“But I am looking forward to the bright side of things because when you consider Theresa May and her dancing, you’re 10 times better than that! So well done,” he added in a swipe at the former Prime Minister.
