1. Taylor Swift, Demi Lovato and Dr Kuke's attorney weigh in on #FreeKesha

Dr Luke has kept silent so far and has not been charged, with his lawyer issuing a new statement refuting Kesha's allegations.

If you were that kid who answered 'astronaut' to the 'what do you want to be when you grow up?' question, now's the time: NASA is calling for applicants. And interest is high - so far, they've received a record-breaking 18,300+ applications - and they have just 14 spots to fill. The level of interest is attributed to the fact that the next crop of space-travellers could be trained for a 2030s mission to Mars.
