Rihanna always has her gorgeousness going on but last Saturday night, the Bajan beauty appeared unhappy and lonely as she stepped out of dinner at Santa Monia’s Giorgio Baldi in LA.

With Chris Brownback and forth rehab – paying for what he did to her in 2009 and her clothing line, River Island kicking off really good, plus she just ended her successful Diamonds Tour, one would think Rihanna should be the happiest girl on the planet but that Saturday-night-look said otherwise.

RiRi wrapped herself up in some dark jeans, over-sized Nike sweater and it’s obvious she’s ditched her short sexy haircut for a fresh head of wavy hair. She looked like the Rihanna we first knew years ago – innocent, no tattoos popping out and well composed even without guards or reps.

Well, we just wonder what’s going on with the award winner; is she just living la vida loca or she’s got something bothering her- like still being so single?
