I've got no filter. It's got me into so much trouble

Alan Carr is back for a sixth series of Interior Design Masters. He tells RACHAEL DAVIS about the revamps that leave him struggling to keep a straight face

- 

ALAN Carr's signature sense of humour has made him something of a national treasure.

Outside of the comedy circuit, he's been getting stuck into all things interior design in shows like Amanda & Alan's Italian Job and Spanish Job, which he presented alongside Amanda Holden, and Interior Design Masters, which is soon to return for its sixth series on BBC1.

Once again Alan, 48, is welcoming 10 interior designers on the ultimate crash course, tasking them with transforming a range of spaces for discerning clients across the country, with their design creations being judged by guru Michelle Ogundehin and a bunch of celebrity guest judges.

Ahead of the show's return, let's find out more from the hilarious host.

Alan, this is the sixth series of Interior Design Masters - what keeps you coming back?

I think the way they push the envelope, just keeps me excited in it. Because it is the sixth series now, and I think they need to excite me, they need to excite the designers, and I think they need to excite the audience. So that's why I keep coming back. It's a laugh, and it's a giggle, you know?

You can tell you're having fun! Tell me about some of the projects in this series

We're doing youth hostels, and then we also do a dog's transition room at Battersea Dogs & Cats Home.

We do comedy clubs up in Edinburgh. We do quirky cottages in Portmeirion for the final, which is so surreal, so fabulous, so fantastic.

Battersea Dogs & Cats Home was heart-wrenching for me, because, you know, you're trying to be on your game, and then you've got these dogs!
