THE 23-year-old pop superstar was spotted checking into the five-star Merrion Hotel on Friday night.
It was a flying visit for the Diamonds singer who promptly checked out again on Sunday morning after enjoying a relaxing weekend in the capital.
Rumours were circulating that the Bajan songstress was in Dublin for a recording session in advance of her world tour in March.
Rihanna had previously recorded the vocals for her hit single Love The Way You Lie in Temple Bar's Sun Studios in 2010.
The star's collaboration with rapper Eminem went on to top the US Billboard charts.
However, an industry source last night denied she had visited the Dublin studio and described the singer's Dublin stopover as a "holiday visit".
There was no sign, however, of the singer's on/off boyfriend Chris Brown during the visit.
This isn't the first time that Rihanna has opted to stop over on Irish shores.
In 2011 she famously shot the video for We Found Love in Bangor, Co Down, alongside male model Dudley O'Shaughnessy.
The singer writhed around in a field as she filmed several steamy scenes for her video. But Riri's antics proved too hot for land owner Alan Hughes.
The DUP councillor pulled up in his tractor in the middle of the shoot and asked the songstress to put on some clothes.
Speaking at the time, he said: "I thought it was inappropriate. I requested them to stop and they did. I had my conversation with Rihanna and I hope she understands where I am coming from."
Despite her run-in with Mr Hughes, it seems Rihanna continues to have a soft spot for Ireland and particularly Dublin.
Last year, the singer threw a Thanksgiving dinner for her entourage in Dublin.
Rihanna treated her band and dancers to a traditional dinner at O'Donoghue's pub on Baggot Street.
The Rude Boy singer had food from French bistro Hugo's ferried across the road to the traditional pub.
She will be returning to Dublin this June as part of her Diamonds Tour and will perform at the Aviva stadium.
