On Monday night she was pictured sitting on her close friend Katy Perry’s lap.

But just the day before, Rihanna was getting cosy with another female friend..

The 25-year-old pop star was enjoying a day of partying with ‘It girl’ Debby Coda in Miami, Florida.

The Diamonds singer is pictured smacking a rather large kiss on the blonde’s cheek – and Debby duly returned the favour.

The tactile display of affection was evident in a slew of Instagram snaps Debby posted online.

In one frame, Rihanna was seen holding Debby’s face while her platinum-haired friend kissed her.

The Ciroc Brand Ambassador also took time out to gush about her Grammy Award winning pal.

‘I love this woman so much. We literally met when we started our careers and I’m honored to have witnessed and experienced some her amazing journey and so proud of the young girl,’ she wrote.

Another snap also shows the two ladies sipping on some cocktails, with Debby writing: ‘My boo @badgalriri and me enjoying some #BLACKGOLD we #daywalkers #drinkwithusyouknowwegotit.’

For the outing, Rihanna dressed casually in an American Flag T-shirt from American Apparel and a pair of tiny cut-off shorts.

She had coiffed her shorts curls and wore an application of signature red lipstick.

Following her Miami trip, Rihanna moved onto New York City to attend her other gal pal Katy Perry’s album pre-release party.

She was seen sitting on the I Kissed A Girl singer’s knee as they partied the night away.

The pair looked like they were having a great time as the Barbadian beauty supported her friend at the soiree.

And the event was going down a treat, with the superstar duo unsurprisingly stealing all the attention.

Katy, 27, made an effort for the event, donning a black and white jumper, an admirably high cut leather skirt and boots.

Rihanna meanwhile wore a black T-shirt and Jeans, though she courted controversy by carrying a cannabis leaf embossed handbag.

Katy’s fourth studio album, Prism, is due out in October, but the single Roar was leaked online Saturday.

It will be officially available on iTunes by midnight Monday.

Meanwhile, Rihanna just finished her Diamonds tour and is currently enjoying some down time.
