Liam Payne called Louis Tomlinson a "f****r" after he got mistaken for his One Direction bandmate.
The 22-year-old singer took to Twitter to complain that after five years in the band people still mix him and Louis, 23, up but joked he would take it as a compliment.
He wrote: "5 years gone and still getting called Louis in places. I'll take it as a compliment @Louis_Tomlinson see you at work f****r."
Meanwhile, One Direction - which also includes Harry Styles and Niall Horan - are preparing to go on an extended hiatus next year but they have all insisted that they will return.
Louis previously said: "We've had a very intense schedule. Five years, five albums, four tours ... I'm sure it appears alarming when we say we're going on a break, but in reality, it's such a normal thing. If you look at other bands and other artists, they [go on breaks] all the time. It really isn't as big and dramatic as it's been made out, but our intention and our love is for the band and that's always going to be the case. I hope so, anyway."
"I think we deserve a little break. In reality, it's going to be an exciting time for all of us to do our own thing and it's actually very exciting for each other, you know? It's going to be exciting for us as individuals to see what we each end up doing. And I'm of course going to be very supportive of that and that's the idea that's pretty exciting, as well."
