Rihanna horsed around at the beach with one of her brothers in her native Barbados on Thursday, and RadarOnline.com has the pics of the sexy star.

The 23-year-old Umbrella singer -- looking fab in a teenie-weenie red and orange bikini -- is spending the holidays at home with her family after wrapping up her grueling  six-month Loud tour across North and South America and Europe.

But her trip back home is not all for play. Tomorrow, she’ll be headlining a private New Year's Eve party at the posh Sandy Lane resort in the Barbados.

2012 promises to be a big year for the star.  She’ll make her film debut in the sci-fi thriller, Battleship, which hits theaters in May.

We're use to seeing Rihanna with wild hair and her sometimes outrageous fashion statements -- and fortunately, Monday was no exception!

The 23-year-old What's My Name singer sported a strange and very colourful pair of striped knit trousers as she chilled on the beach with friends in her native Barbados.

RiRi paired her colorful pants, thought to be by Missoni, with a tan bikini top and a pair of over sized brown sunglasses while letting her gorgeous hair down.

Rihanna made a sexy splash in her homeland on Thursday, stripping down to an uber-skimpy bikini and braving the waves on a jet ski - and RadarOnline.com has the photos.

The Barbadian beauty left little to the imagination, showing off her hot body in a white hot, bandeau bikini, which was held together by flimsy strings - not your typical swimsuit for a day of water sports!

It was a photograph that shocked even Rihanna's over-exposed fans - a man grinding behind her as she bent seductively over wearing only a skimpy Carnival outfit in her native Barbados.

But RadarOnline.com has learned that the man in question, Negus Sealy, was in fact her 'first love' and as their 'dirty dancing' suggests the pair have gotten really friendly again.

Superstar Rihanna - who split-up with LA Dodgers baseball star Matt Kemp last year and was rumored to have been seeing hip-hop singer Drake - is back with Sealy.

Excuse us while we catch our breath.

Rihanna was the ultimate hometown hottie in her native Barbados on Monday, where the 23-year-old pop star showed off nearly every luscious inch of her body in the annual Kadooment Day parade.

The hip-hop beauty, clad in a red, barely-there costume, showed off her flat tummy, mile-long legs, tiny tattoos and a tush that holds up from California to the Caribbean.

Turns out Rihanna’s got more under her umbrella that we originally thought.

The trend-setting S&M singer's father, Ronald Fenty, fathered three children pior to his marriage, meaning RiRi's got three half-siblings and two nieces who previously went unaccounted for.

They are: half-sisters Kandy, 32, and Samantha, 30; half-brother Jamie, 27; and nieces Brandy, 14, and Crystal, 11.
