You can always rely on your best friend to drop you in it - and Rihanna's pal Melissa Forde did it in the BEST way.

The stunners are soaking up the sun together in RiRi's hometown of Barbados - and the stunner couldn't resist doing a bit of topless sunbathing.

Why not? She's at home after all.

The daring singer was snapped by her BFF in nothing but some very tight grey Puma boxers this weekend, showing off major side-boob and those world-famous tattoos.

One more turn and Melissa could have exposed far more of her friend than she bargained for.

In one snap, Rihanna is stood in front of the sea view, showing off her toned bum and bare back with her hair loose and wavy down her back.

But another goes one step further and reveals her entire winged tattoo and as much under boob as is possible in the tiny boxer shorts.
