Rihanna's trip to the beach in Poland on Sunday (07Jul13) was ruined when the pop star was mobbed by a huge crowd of fans.
The We Found Love hitmaker and her best friend Melissa Forde donned their bikinis to soak up the sun in Sopot, but the pals weren't able to relax on the shore once locals spotted the superstar.
Rihanna and Forde put up giant umbrellas around their sun loungers to block out any onlookers and they posted a video of their view from their makeshift enclosure on Instagram.com.
In the clip, the camera pans around to show the rows of umbrellas while Rihanna explains, "This is what a beach day in Poland looks like. Getting as much sun as possible. Caged in like a f**king animal!"
Rihanna also posted on the site, "Tried to have a beach day, that was a fail!"
The singer was in the country for a concert in Gdynia later that day.
