LeAnn Rimes and many other celebrities are deeply disturbed over the "horrific" slaughter of people at a college in Oregon.
A 20-year-old male reportedly entered Umpqua Community College and began shooting at staff and students, leaving 13 dead and an estimated 20 others injured.
As the shocking news of another US campus shooting incident unfolded, stunned celebrities took to Twitter to express their feelings.
Singer LeAnn Rimes tweeted: "Reading the news about the #OregonShooting horrific! My heart goes out to the victims and their families".
Sara Bareilles added: "Oh God. My head is reeling. I'm so sorry and so sad for the victims in Oregon. My prayers are with you."
Police raced to the scene and engaged in a shoot-out with the suspect, who died in the exchange. No cops were hurt in the incident, but the loss of life has left stars feeling deep compassion for the victims' families.
Actress Olivia Munn tweeted, "Sending my love and prayers to the victims and families of UCC", while fellow screen star Eva Longoria posted, "My hearts and prayers for those in Oregon."
Comedienne Ellen DeGeneres and actress-turned-reality TV regular Lisa Rinna also weighed in on the shooting, while band Maroon 5, who are currently on tour in New Zealand, paid tribute to slain citizens by posting: "Our hearts go out to the victims of the #UCCShooting, all the way from here in New Zealand."
The Oregon massacre is the latest school shooting to rock America following similar gun atrocities at Sandy Hook Elementary School in Newtown, Connecticut in 2012, and Arapahoe High School in Denver, Colorado in 2013.
On 23 July (15) a 59-year-old gunman killed two women and injured nine other people at a theatre in Louisiana during a screening of comedian Amy Schumer's new comedy Trainwreck.
And on Monday 3 August (15) she paid her condolences in a detailed speech about gun violence.
"No one wants to live in a country where a felon, the mentally ill or other dangerous people can get their hands on a gun with such ease," she told reporters in New York City, according to the New York Post. "The critics scoff and say, 'Well, there's no way to stop crazy people from doing crazy things,' but they're wrong. Preventing dangerous people from getting guns is very possible, these shootings have got to stop. I don't know how else to say it."
