As one of the best-selling pop artists of her  time, she’s definitely got the world in the palm of her hands.

And just to prove how big of a superstar she  is, Rihanna opted to go trouser-free as she shopped in Monaco on  Friday.

Trouser free and loving it: Rihanna stepped out for a  quick shopping trip in Monte Carlo, Monaco on Friday wearing only a swimsuit and  a lacy shirt

The 25-year-old is currently in Monte Carlo  with friends, and before heading off of an afternoon yacht ride, opted to look  for a new pair of shoes — wearing only a sheer long-sleeved top and a custom  made swimsuit gifted to the singer by New York City designer Matthew  Zink.

The Barbados-born singer was certainly the  only one in beachwear as she strolled through the shopping centre, drawing  attention as much for her exposed legs as for her fame.

The black one-piece spares no expense at  exposing her fit figure, lengthening her legs with a high-cut bottom and  covering up her chest with a string-tightened top.

Showing some skin: The Only Girl singer flashed her  legs, and her sheer top didn’t do much cover-up either

Scene stealer: The crowd parted as she sashayed through  the indoor shopping centre

And making the piece even more unique was a  bedazzled letter ‘R’ at the top of her lower back.

She wrote on her Twitter Friday  morning:  ‘#Monaco #YachtLife #BoatzNHeauxz @charliebymz I finally put  this bad ass piece  on for your Birthday!!’

The Diamonds singer didn’t much try to tone  down her outfit, styling her half-shaved  bleached blonde hair in soft  beachy curls over her shoulder.

That explains it: Rihanna’s choice of swimwear looked  less out of place as she arrived for the boat ride

Late start: She was spotted partying into the early  morning hours the night before

Later the Umbrella songstress shared snaps  aboard a yacht with her friends as they sailed off from the port of Monte  Carlo.

‘#Fridayz #monaco kingspleasure,’ she  wrote.

Rihanna’s extended her stay in the small  European principality, having played a  show in Monte Carlo on Thursday night  and taking a few days off until  her next performance in Manchester on  Monday.

Little black cover-up: RiRi kept herself modest as she  held a small black handbag close to her waist

Are these a good fit? She seemed to be quite fond of a  pair of white and gold-studded strappy heels

Showing them how it’s done: The 25-year-old turned up  the volume with her bleached blonde hair

The night before her shopping  excursion she  was spotted hitting the dance floor at Jimmy’z Monte Carlo with Nicole  Scherzinger’s ex-boyfriend Lewis Hamilton.

The race car driver only broke up with the  Pussycat Doll earlier this  month, ending their five-year relationship and  one-time engagement.

A DJ at the club told RadarOnline that the pair appeared cosy, ‘drinking and having fun’ for several hours  among a larger group of friends.

‘Rihanna stayed about an hour and a half with  Lewis,’ he said. ‘He came with his friends but when she arrived they were  together.’

No bad angles here: The swimsuit flattered every inch of  her fit figure

Also on Friday RiRi debuted her latest  campaign for beer brand Budweiser.

Rihanna can be seen directing a photo shoot  for her fashion range in the advert.

The commercial kicks off with Rihanna  scribbling something in a notebook  while being driven to the studio, perhaps  coming up with design ideas.

The words: ‘Make a statement. Then make it  bold. Make it with attitude. Make it real. And make your mark,’ flow  throughout.

Ocean commotion: Rihanna drew quite a pack of on-lookers  as she and her friends headed of to their yacht

The commercial, shot by director Mark  Romanek, finishes with the poignant message: ‘It begins and ends with what you  make.’

At the end of the artistic advert, the  Barbadian born beauty is doing what she loves best, performing on stage in  concert.

The thirty second spot is set to her latest  single Right Now and is part of Budweiser’s Made For Music  campaign.

Perfect fit: The swimsuit was gifted to the star by  clothing line Charlie by Matthew Zink

Anchors away: The singer is weekending in Monte Carlo,  where she performed on her world tour on Thursday
