Chris Brown's new neck tattoo has the blogosphere speculating as to whether the ink is a disturbing homage to his ex-girlfriend Rihanna and their 2009 domestic dispute.

The black and white inking of a female's face with a bruised right eye and a stitched-up mouth was first noticed over Labor Day weekend when Brown, 23, stepped out for an event at Las Vegas' Hard Rock Hotel and Casino. Though the tattoo bares a resemblance to Rihanna (and the photo of her following her physical altercation with Brown), a source close to the R&B singer tells TMZ that the image is of "a random woman."

Brown was charged with domestic abuse after assaulting Rihanna the night before the 2009 Grammy Awards. She was hospitalized following the incident and was covered in bruises on her face.

Despite their tumultuous history, Brown and Rihanna have reconciled. On Thursday night in Los Angeles, the exes shared a kiss after Rihanna won Video of the Year at the MTV Video Music Awards.

Rihanna, 24, also debuted a tattoo this week, hers reportedly a tribute to her late grandmother who died earlier this summer. The S&M singer shared a photo of the new ink on her Instagram this past Sunday with a message that read: "Goddess Isis — Complete woman — Model for future generations — #Grangrandolly — always in and on my heart#1love." The tattoo is located under her breasts and is an image of the goddess Isis.

UPDATE: Brown's rep tells The Insider that the tattoo is not of Rihanna, saying in a statement: "His tattoo is a sugar skull (associated with the Mexican celebration of the Day of the Dead) and a MAC cosmetics design he saw. It is not Rihanna or an abused woman as erroneously reported. It is peeling right now."

Tattoo artist Peter Koskela says of the ink, "It’s a sugar skull based on the MAC design that Chris brought me."
