Dua Lipa is releasing new music and holding a surprise London launch event

“Tell me all the ways you need me,” sings Lipa. The video then ends by listing seven numbers: 4 8 9 9 14 15 21, which don’t seem to form a pattern or a mathematical sequence. Convert each number into its corresponding letter of the alphabet, though, and you’re left with DHIINOU – an anagram for Houdini, who famously loved unlocking things.
