Now this is an interesting question, because there seem to be a whole range of different answers to it, depending on where one is looking. And, of course, it depends on whether, which is presumably the case, X Factor star JLS is meant, or the JLS as in Jamie Lynn Spears. An unlikely thought, but it is there.
This is where it gets interesting. Spirit Artists, a major London booking agency who, to paraphrase their words, do not directly represent JLS, but are able to arrange bookings through their agent or booking manager, claim that the artists on their list cannot be booked for personal appearances or Charity events. According to them, the minimum fee for these artists is $100,000, rising up to $10million, depending on the artist. Metro, on the other hand, recently announced that the band can be booked for around $47,728. This puts them about $1,861,376 behind X Factor sensation Lewis, by the way. Other sources believe it could be even less. It looks like the best way to find out the correct figures is to contact their agent, Andrew Pountain. He can be contacted directly through the Industry Music Group site, which makes it a quite easy and reasonably straightforward mission.
Just in case she's the one in question, a little research was done here. Sadly, no figures could be determined. The fact that she has a net-worth of around $5million and can earn $1million for a photo-shoot, however, does hint at a potentially astronomical figure. Unless, of course, rumors that she is in retirement are true, and she decides to do a cheap gig just for fun. The odds of that happening, sad as it may be, are anybody's guess.
