Rihanna's Bird Flipping Night at Giorgio Baldi

Greeting the cameras with a double dose the bird, Rihanna was spotted giving a not-so-kind greeting to paparazzi while leaving Giorgio Baldi in Santa Monica, California on Friday (March 23).

As if the plunging denim top didn't show off enough skin, the "Found Love" singer knotted up her shirt to reveal her midriff as she walked away laughing after putting her pointy white-nailed middle fingers in the air.

After Rihanna was spotted this week making a late night trip to see Ashton Kutcher at his home, reports are surfacing that the pair have been seeing each other for eight weeks.

"The flirting began as soon as Rihanna and Ashton met and swapped numbers," a source told The Sun. "That moved onto texts and arranging to meet. They snuck off to a Santa Monica hotel a few weeks ago."

The duo both share public break-ups with their ex's Chris Brown and Demi Moore, so they "thought it would be best to meet in secret."

"Rihanna has told friends he's funny and cute. Both of them love a good time and think they're too busy for anything serious just yet. She's starting to enquirer about Kabbalah sessions with his rabbi," The Sun's insider adds.
