Stacey, 31, and Kevin, 36, took on the role of opening the show with their Salsa to the song Gina G’s Ooh Aah Just A Little Bit tonight.
The pair seemed to impress the Strictly Come Dancing judges, landing a score of 33 out of 40.
The fast-paced routine, choreographed by professional dancer Kevin, saw the BBC broadcaster arrive on the dance floor via a giant stick of rock prop.
Following their performance, body language expert Judi James shared her thoughts with Express.co.uk.
And, while Kevin may be the professional dancer, it seems that the body language specialist thought that Stacey’s best bits were when she was taking on a leading role.
She told Express.co.uk: “Stacey has to be the most entertaining and exciting performer in the competition.
“At times she looked like she was still on the girls night out we saw in her clips but she fizzed her way through this salsa and it has to be said her best bits came when she danced solo, up front and leading the group.
“Kevin seems to just hold on for the ride now although he did shush her quickly when she began to tell the judges about the mistakes she made.”
The body language expert also revealed: “The duo arrived in a state of childlike excitement at the thought of opening the show in Blackpool. Stacey giggled and winked while Kevin looked super-hyped.
“Their routine began in some chaos with Kevin dancing with other girls while Stacey descended on a giant stick of rock. We were spared the sight of her dismount but the show really started when she hit the floor.”
Reflecting on Stacey’s reaction to the judge’s comments, Judi added: “Her points were partly lower than expected and it showed in Stacey’s facial expression as she sucked her lips in and pulled a denial gesture wince of disappointment.”
However, it seemed head judge Shirley Ballas was delighted with their moves, telling Stacey: “Those lifts, that rhythm in your body… I mean you brought it today.”
Stacey and Kevin scored a total of 32 out of 40 with their waltz last week.
The duo’s performance was to Moon River, which was originally sung by Audrey Hepburn.
Stacey shot to fame with her array of documentaries which are broadcast by the online platform BBC Three – and her efforts have also seen her be given an MBE.
She first appeared in a TV documentary titled Blood, Sweat and T-Shirts which was about workers’ rights in the garment industry.
The star was later given her own series, which tackle topics ranging from social justice issues to the environmental impact of fashion.
So, how much cash has Stacey made from her self-titled programmes? What is her net worth?
It’s not publicly known what Stacey’s net worth is, however one website has claimed she could have a huge fortune in her bank.
According to ArticleBio, the star’s net worth could be more than $1 million – which equates to around £778,820.
Strictly Come Dancing 2018 continues tomorrow night on BBC One at 7.20pm.
