One Direction re-visited the studios of Alan Carr's Chattyman this week for another giggle, and after Zayn Malik's dance-off with Alan last time they popped in, this time the whole group got involved.
The chinos have been replaced with some moody looking wine-coloured trews - which actually look almost exactly the same as Alan's. Maybe there was an offer on, or Louis put some purple pants in the chino-wash or something.
Anyway, click next to see the rest of the pictures of the dancing!
Alan Carr is on Channel 4 this Sunday at 10pm
Love how Louis is gently putting his arm on Harry's waist there.
