Strictly Come Dancing could be thrown into jeopardy as Tyler West is being forced to miss several days of rehearsal time.
The DJ and broadcaster, who is currently competing in the show alongside professional dancer Dianne Buswell, shared his worries on BBC's Strictly: It Takes Two.
Before the live show which takes place every Saturday, each contestant goes through a gruelling routine schedule as they perfect their dance moves.
However, Tyler will miss around two days of his week in order to attend his brother's wedding on the other side of the globe.
Speaking to host Rylan Clark, he said: "My calendar is just not looking good is it," after Dianne appeared to take a pop at him.
The red-headed beauty said: "I'm really enjoying this, we've got a lot of work to do, right Tyler?
"But I'm really enjoying this one, so hopefully all goes well and you get back from Mauritius in time, we'll be good."
While Tyler added: "My brother is getting married, so I've got to fly out to Mauritius, for 13 hours, I'll be there nine hours, then I'll do 13 hours to come back."
Following his admission, Rylan praised the star saying: "Dedication, we like to see it," as the audience applauded.
After the announcement confirming that Tyler and Dianne would be dancing to the official Doctor Who theme tune, Christopher Eccleston, who played the ninth doctor, shared a video message for the pair.
The actor said: "Tyler, hello Dianne, I've been running the tune through in my head to try and work out what moves you're gonna do and I can't.
"So, to paraphrase James Brown, I don't care how you dance, but however you dance, it's got to be funky – good luck."
"I'll give him funky, I'll give him something funky," exclaimed Tyler after watching the video clip, before saying: "I'll try my best, that's mad isn't it, now I feel the pressure, it's hot in here!"
During the live show on Saturday, Tyler revealed his family were not in the audience as they had already flown out to Mauritius ahead of his brother's nuptials later this week.
Speaking previously on BBC Breakfast, Tyler said: "I think I’ve put my body through the paces and then I thought, Lewis, my brother, I’m the best man for his wedding, so I’m flying to Mauritius for, I think about nine hours.
"I kept the schedule light this year," he joked after running the London Marathon.
