Curtis Pritchard might be in hot water with girlfriend Maura Higgins after letting slip her secret live on Good Morning Britain.
The Love Island star, 23, appeared on the ITV programme with brother AJ to speak about their new dance tour.
He also spoke about his relationship with Maura, which he gushed was "incredible".
"I've been so lucky with everything," he told hosts Kate Garraway and Ben Shephard. "She's gone to Ireland, I believe, but I can't say what for because it's a surprise."
However he left the presenters baffled when he revealed what it was anyway.
"I don't want to say in case her brother's watching but it's a surprise birthday party for her brother," he revealed.
"Is it? You've ruined it!" Kate exclaimed.
Ben added: "You say you don't want to say it and then you've said it."
"I'm hoping he's not watching it!" Curtis exclaimed.
He also spoke about becoming a WeightWatchers, now called WW, ambassador while Maura is working for McDonalds.
Curtis insisted that the diet wasn't about "banning" things like McDonalds, saying: "It's all about being able to lead a healthy lifestyle."
AJ later opened up about how his Strictly training was going with Saffron Barker.
"We've worked so hard in the week," she said. "She's put the hard work in."
