Between the two of these powerful women lie a single monicker, incredible talent, two massive multimedia empires, and over $3billion in the bank.

But earlier today they were just two girlfriends catching up in a truck as the 24-year-old pop star gave the 58-year-old talk show host a guided tour of her hometown of Barbados.

‘Look who popped up in my Hometown BARBADOS #topnotch,’ Rihanna tweeted tonight to her 23.6million followers.

And in the same instant Oprah posted, ‘Look who’s driving me around Barbados!’ for her 13million followers.

Oprah is taping an exclusive interview with the provocative singer for her talk show Oprah’s Next Chapter, which will air on August 19 on OWN.

The twosome, both dressed in green, will surely have much to discuss as Rihanna’s had an action-packed year of scantily-clad Twitter pics, a rumoured relationship with ex-boyfriend Chris Brown, and she was allegedly the catalyst of the massive bar brawl at New York club WIP where several people were injured.

Rihanna also posted a number of black-and-white pictures from her Egyptian-themed act from her many festival appearances this summer.

The You Da One singer, who’s nominated for five MTV VMA awards, just returned from a well-deserved break in St.Tropez.

Last week it was reported that Rihanna and her ex-boyfriend Chris had enjoyed a ‘late night meeting aboard his luxury yacht’ according to Look Magazine.
