Rihanna posed for photos with Melissa, her best friend, during the Mayweather VS Guerrero fight at the 40/40 Club in New York City last night (May 4).

After having dinner with her friends, RiRi was photographed at the 2013 NFL Draft Party at Greenhouse last night (April 23) in New York City. She posed for photos with Wale and DJ Khaled.

Last night (March 22) Rihanna performed at the United Center in Chicago, Illinois.

Earlier that day, she visited Barrington High School (scroll down for more information).

Rihanna took the stage at Barrington High School moments ago for her much-anticipated visit. Her fans greeted her with wild applause and Beatlemania-type screaming.

“Thank you guys for coming and waiting,” the Barbadian signer said, before paying tribute to the school’s charitable works.

The school won the visit with Rihanna – hours before she’s due to perform at the United Center – after winning a contest she sponsored. She invited schools to produce videos set her “Diamonds” single that would highlight charitable work. Barrington High’s video, produced by students of the BHS-TV class, is a montage of shots that shine a light on several different philanthropic initiatives in which the school participates. Among many other service projects both local and nationwide, the school has assisted tornado victims in Joplin, Mo., and Natives American who live on a reservation in South Dakota.

“With a whole lot of polishing and collaboration, we can all shine bright like a diamond,” says the narrator of the video.

Rihanna’s website said the contest was intended to honor the “most creative and inspiring lipdub or video that includes a giving back to your community (and world!) message.”

About 2,500 people assembled in the gymnasium of the northwest suburban high school awaiting Rihanna’s arrival.

A school official announced that someone in the crowd will win an autographed Rihanna CD and tickets to her show tonight at the United Center.
