Kevin Clifton has said he's "very annoyed" at Joanne Clifton's Strictly Come Dancing success this year.
But he's still a "really proud" older brother!
The siblings are going head to head on the dance floor this series, just like the celebs.
Both are still in the competition with Kevin partnered up to singer Louise Redknapp while Joanne is with sports presenter Ore Oduba.
And Joanne has already got one up on her bro.
The current reigning Christmas Strictly champion declared gleefully last month: "I'm the only Clifton to have lifted the trophy! That's in Grimsby on my mum's mantelpiece, just to remind Kevin."
Chatting on It Takes Two, Joanne added: "There is rivalry. yes, Kevin, you're going down."
Since then Joanne has stuck to her word and regularly beaten her brother on the leaderboard with their respective celebrity partners.
Speaking to OK! magazine this week, Kevin admitted "She's on fire! It's very annoying!
"I'm really proud of her. I think she has a renewed sense of determination and is bringing out her best work. But don't tell too many people I said that!"
As for for Kevin's own chances in the competition, the pressure is on after making the final in every series he's appeared on so far.
"It's too early to start thinking about the final. the bar has been raised really high this year," Kevin said.
Meanwhile, as well as his sister, Kevin of course works on the show with wife Karen Clifton who was eliminated after Will Young left the show.
"She's okay," he said. "It was a shame he left, as I thought he had a lot of potential. But it's important that he's okay, whatever he has going on."
Strictly Come Dancing 2016 is back this Saturday and Sunday night on BBC One.
