Kelvin Fletcher has revealed he's been struggling in training for his next Strictly Come Dancing routine.
The Emmerdale actor only joined the show two weeks ago, replacing injured Jamie Laing.
Despite being a late addition to the line up, Kelvin stormed to the top of the leaderboard in the first live show with an impressive Samba.
However his next routine - a Waltz to What the World Needs Now Is Love - is proving more tricky to master.
"I've been feeling dizzy," he told Zoe Ball on It Takes Two. "Oti [Mabuse] said the Samba was one of the hardest dances but the Waltz feels even more difficult.
"It feels more technical. It's a different extreme."
He added: "It's not as physically intense but I feel it's more mentally exhausting and I've got a real thing with dizziness and spinning."
Also appearing on Monday night's spin-off show were Anneka Rice and Kevin Clifton.
Preparing for their second routine, Kevin teased: "I think Anneka is going to surprise herself and everyone else when it comes to this. I think there's a secret ballroom girl in there."
As always there was no elimination in the first week but the judges' scores carry over to this weekend where the public will get their say for the first time.
The judges' marks and viewer votes will be combined to determine the first two celebs to face the dance off where one couple will be sent home.
Following Saturday's firs show, Kelvin's odds have crumbled into 7/5 from 7/1 with bookmakers BoyleSports, overtaking previous favourite Karim Zeroual, who is out to 7/2 from 10/3 despite a high score of 31 following a cha-cha to Shawn Mendes.
James Cracknell meanwhile looks up the creak without a paddle after a big gamble on him being the first casualty of the new series.
His Tango to ‘Gold’ by Spandau Ballet won’t see him on the podium any time soon after a week-low score of 11 saw him plummet into 11/10 from 11/2 to be the first contestant axed.
Lawrence Lyons, spokesperson for BoyleSports said: “James Cracknell’s chances look sunk after he was backed off the boards to be given his marching orders first, but at the right end of the betting it’s all about Kelvin Fletcher. He has set down an early marker and is now the dancer to beat at 7/5 from 7/1.”
Strictly Come Dancing is back this Saturday night on BBC One.
The first results show will air on Sunday.
