The 13-year-old is a huge fan of the boys, so when Johnny found out they were in town, he pulled some strings and made her boy band dream a reality.
“He brought out his piano and guitars for the boys to test and they had a little jam session," a source told UK tabloid The Sun.
“Lily Rose just watched with her blushing mates while her dad temporarily joined the world’s biggest boy band.”
Things must have gone pretty well — Johnny has already invited them back for a whisky when all the boys are old enough to drink it.
Best dad ever!
