The singer is currently touring her fifth studio album Loud in the UK, while promoting her sixth opus Talk That Talk at the same time.
It has been reported that the star was grumpy on the set of her new video 'You Da One' after suffering from a severe lack of sleep.
A source told Metro: "She was complaining she hasn't had any kip in days and was a bit crabby."
Recent reports said that the 23-year-old was booed for turning up late to her UK concerts and had allegedly been put on a 24-hour health watch following a supposed breakdown backstage.
The Bajan performer's latest set Talk That Talk reached number one on the UK chart and number three on the US Billboard 200 upon its release last month.
