Rihanna is not one to stick with one look for too long, so the pop star has yet a new hairdo - a half shaved head with full long waves. This hairstyle is similar to the one she had before her latest pixie cut, except the tresses aren't nearly as long.

Rihanna revealed her new look via Twitter with the caption "Diamonds." Fans immediately assumed that the hairdo was for the upcoming "Diamonds" music video. Prior to the photo upload, the singer tweeted another photo with the caption, "Heading to to set."

Rihanna released her latest single last month, and is expected to drop the accompanying video any day now. The song's lyrics are uplifting and hint her feelings about her rekindled lover Chris Brown.

Lately, Rihanna has been tweeting many suggestive messages that seem to refer to Brown. Fans assume that the tweets are bits of lyrics off her new album, "Unapologetic," which hits shelves November 19.

"I found the one, he changed my life...But was it me that changed and he just happened to come at the right time? #UNAPOLOGETIC"

"I don't wanna give you the wrong impression... I need Love&Affection #UNAPOLOGETIC"

"Together ain't promised forever, let's live in the moment #UNAPOLOGETIC"

"As long as we got each other, die in the moment #UNAPOLOGETIC"

Whether or not those tweets above refer to Chrianna love tales or just lyrics from an upcoming club anthem, the 24-year-old pop star is revealing juicier details of her relationship with Brown through a much clearer method: a public date night.

Rihanna and Chris Brown were spotted canoodling at Brown's Qubeey event. Rihanna snuggled under Brown's arm and the two whispered to each other. They shared drinks and a cigarette. The couple was engaged in what seemed to be an invigorating conversation.

Watch the couple in action in the video below:

Although Rihanna and Brown were spotted together, it may not be their official debut as a couple. According to close sources, Rihanna is worried that her "Unapologetic" album won't sell due to her decision of re-entering a relationship with her former abusive boyfriend. The couple is allegedly staying low until the time is right. A red carpet appearance together would be much more significant. 

Meanwhile, Brown's rejected ex, Karrueche Tran, seems to be doing ok. The Vietnamese food blogger has been tweeting about dining with friends and participating in charitable projects.
