Her romance with on-off boyfriend Chris Brown is believed to have soured in recent days after the couple refused to acknowledge one another at a Los Angeles nightclub on Wednesday evening.

So Rihanna’s choice of amber dress was a somewhat telling colour as she headed out alone on Valentine’s Day.

Perhaps giving a not-so-subtle hint that she is preparing to put the brakes on the pair’s tumultuous relationship, the 24-year-old singer stepped out solo as she attended Ne-Yo’s concert at the Staples Centre in Los Angeles on Thursday night.

With her musician beau nowhere to be seen in spite it being the traditional day of romance, the Diamonds hitmaker’s lonely appearance will have no doubt set tongues wagging that she and Chris are well and truly off once again.

Although Rihanna was without her man on her arm, the Bajan beauty made sure she looked utterly showstopping as she headed out for the evening.

Her choice of bright orange draped Grecian-style dress perfectly complemented the singer’s slender frame, while being a more demure choice than her usual flesh-flashing X-rated outfit choices.

The starlet teamed her sexy dress with a pair of classic gold strappy sandals and matching earrings as she wrapped up against the winter chill in a chic black fur coat.

A slick of dramatic pillar box red lipstick, bronze make-up and her brunette locks flowing in loose waves down her back completed Rihanna’s night out look.

In spite of not having her beau by her side, the star evidently chose to make the most of her evening out on the town by heading to nightspot Club Bloc after the gig.
