Rihanna wears a maroon hoodie and denim cut-offs while clutching an armful of sweets after all-day party

There's no denying that she's got stamina, and is just as well known for her hardcore partying as she is for her pop songs.
And Rihanna pulled another all-day party session on Sunday, spotted emerging from her hotel clutching an armful of sweets after her night out at Club Space in Miami.
Looking more casual than usual, the stylish star wore tiny denim cut-offs and a maroon hoodie with the word 'pigalle' emblazoned across the front.

The singer, 25, looked like she hadn't got changed or been to bed since her day and night of partying, but had clearly picked up some sugary treats to tide her over.
She seemed to have ditched the bright red lipstick from the night before and covered her make-up free face with a pair of dark sunglasses, with her crop of dark hair left curly and natural.

The hardcore star looked like she was just about ready for some sleep after partying all day and night with her friends.

After a break to her native Barbados, Rihanna reportedly jumped off the plane in Miami at 8am on Sunday and headed straight to the club that she had booked out to celebrate the birthday of her hairstylist and pal Yusef Williams.

According to reports she splashed out $20,000 to secure the club for all of her friends and didn't leave until 4pm that afternoon.

But instead of heading back to her hotel to recuperate in the afternoon, Rihanna made a beeline for the Shore Club Hotel in South Beach for a poolside party, not emerging until the early hours.

Despite her hectic work schedule, the Diamonds star certainly makes time for her partying, proving that she doesn't need much sleep to keep going.

#MiamiMornings Cabbing it out round town since 8 am because I'm bored! On some "taxi driver be my shrink for the hour, leave the meter running" type shit #WhereAmIEvenGoing,' she tweeted after touching down in Miami on Sunday morning.

She was, of course, joined on Sunday by her ever-present partner in crime, bestie Melissa Forde, who was also on the Barbados trip.

Rihanna spent much of her Barbados break relaxing at the beach and posting 'selfies' onto her Instagram page for all of her pals to see.
