Rihanna, Jimmy Fallon and Cameron Diaz Lead Today’s Star Sightings

From the Diamonds World Tour to Late Night studio, the stars have been busy bees in the last 24 hours.

Rihanna hit the stage in Antwerp for the second night in a row as she performed inside the Sportpaleis arena for her world tour. The 25-year-old superstar is due in Paris on Saturday, followed by a string of shows in England.

Stateside, Jimmy Fallon looked ultra dapper in a beige jacket and navy dress pants as he headed to work in New York City. The Late Night host finished off his look with a stylish suitcase and a peace sign (for the nearby photographers).

Elsewhere on the east coast, Cameron Diaz and her co-star Taylor Kinney (not pictured) continued to film scenes for their new film The Other Woman in the Hamptons. Diaz, 40, was spotted holding a glass of wine as she showed off her long legs on some waterfront property.

Back in Hollywood, Hilary Duff went on a dinner date to Madeo with her hubby Mike Comrie, Alyson Hannigan stepped out to support her man Alexis Denisof at a screening of his new film Much Ado About Nothing and John Cho threw the first pitch at a game between the Los Angeles Dodgers and the Atlanta Braves.
