Earlier this week, Cooper set Luke the challenge of interviewing a mystery guest.
So before Luke set off on his quest, we gave him a few hints as to who this person might be...
A lot of you guessed correctly; it was of course the amazing Dua Lipa who was in town for her two sold out gigs at The Olympia.
Without notes and no time to prepare, Luke sat down with the New Rules singer and chatted about Festivals in the rain and writing songs with rude titles!
