Bajan beauty Rihanna has informed her 28 million Twitter followers that she has just finished shooting a "top secret" ad campaign.

The 'Where Have You Been' songstress took to her social networking page earlier today (January 28) and explained that she had just wrapped a new project, writing:

"And that's a #wrap on my shoot for my new #topsecret add campaign!!! #2013 #phuckyobasic."

She then uploaded a couple of snaps from the shoot via her official Instagram account, which show her with bold red lips, a cropped haircut and a statement necklace adorned with Chanel charms (pictured below).

Rihanna added: "#RIHpost sneak peek of my shoot today with mertalas"
