During his recent visit to The Ellen DeGeneres Show, Bruno Mars have a moving tribute to the victims and families of last week’s Sandy Hook Elementary School shooting in Newtown, Connecticut.

The 27-year-old part-Puerto Rican singer, who recently reached No. 1 on the Billboard Hot 100 chart, opened the show by performing “Count on Me,” a single from his debut album Doo-Wops & Hooligans, complete with a ukulele.

Supported by a lone back-up singer, Mars flawlessly belted out the fitting tribute after a heartfelt introduction by DeGeneres, who decided to kick-off her show differently following the shooting that killed 26 people including 20 school children on Friday, December 14, a tragedy gripping not just the community in Newtown, but the entire nation.

“I think we can all agree right now we need a lot of love out there,” said DeGeneres as she introduced Mars.

It’s the latest in a series of tributes to the victims of the shooting…

On Sunday, New York Giants star Victor Cruz marked up his shoes with a special message to honor one of the young victims, who happened to be a big Cruz fan.

On Monday, Christina Aguilera and her fellow The Voice coaches joined the show’s hosts and contestants to perform a song to honor the victims while each holding a placard with the name of a victim.
