The former footballer and her professional partner performed the fiery routine to Bishop Briggs’s version of Never Tear Us Apart, which was rather apt as they ended up becoming stuck to each other.

Neil had to carry Alex across the dancefloor and over to the judging panel at the end of the routine when their clothes became attached
Host Tess Daly was initially unaware as the couple tried to untangle themselves from each other before noticing their predicament.
Jumping in to help, Tess said: “OK we have a microphone malfunction, or is it a sequin malfunction?”
Alex tweeted after the show: “Yes this did happen through the dance but we tried our best to carry on and still do the routine the best we could.”
Their routine drew mixed results from the judges, receiving 26 points overall.
The former Lioness was criticised for looking like she was “churning butter” throughout the routine by judge Craig Revel Horwood, who scored her just four points.
Alex and Neil are now at risk of being eliminated from Strictly this week along with Saffron Barker, who is at the bottom of the leaderboard with them with 26 points.
The YouTube star and dancer AJ Pritchard performed a samba to Walking On Sunshine by the Take Me To Rio Collective.
Her low score comes a week after she was in the dance-off against Michelle Visage, who was booted from the competition.
At the top end of the leaderboard were Kelvin Fletcher and Karim Zeroual, who both scored 38 points from the judges.
Kelvin and his partner Oti Mabuse impressed the judges with a street/commercial routine to Frank Wilson’s Do I Love You (Indeed I Do), a song that the actor said meant a lot to him.
Children’s TV presenter Karim’s emotional contemporary dance to With Confidence hit Drops Of Jupiter with partner Amy Dowden almost had the judges in tears, and they were full of praise.
However, Craig did warn him that his performance lacked “emotional content” to boos from the audience.
It was the second week in a row that Kelvin and Karim both came in joint first place.
Comedian Chris Ramsey and his partner Karen Hauer came in third place with 31 points after he performed his most serious dance yet – a paso doble to Run Boy Run by Woodkid.
EastEnders star Emma Barton tackled a quickstep to Sparkling Diamonds by Nicole Kidman from the film Moulin Rouge! with Anton du Beke, for which they scored 29 points, a drop of eight after their score of 37 last week.
Strictly Come Dancing: The Results will air at 7.15pm tonight on BBC One.
