Ellen DeGeneres has said "a lot of things need to change" following the recent shootings in the US.
The chat show host spoke out following the recent spate of deadly shootings in America, where two black men and five police officers were killed in the last week.
She said: "I think obviously something needs to be done, everybody needs to start respecting one another, in every area.
"There's too much carelessness and disrespect and a lot of things need to change."
Ellen was speaking at the UK premiere of her film Finding Dory in London's Leicester Square.
The animation welcomes back to the big screen the forgetful blue tang Dory who embarks on an adventure with clown fish Nemo and Marlin to try to find her long-lost family.
The film's trailer, which included two women with a pram, sparked speculation from fans that Pixar/Disney had included a same-sex couple in the animation.
But Ellen, who was joined at the event by her wife Portia de Rossi, quashed the speculation, saying: "I hadn't looked for that and I'm pretty good at spotting lesbians so I thought I should have seen it.
"I think it was just a woman with a short hair cut. I think they assumed everyone with short hair is a lesbian - that's a bad assumption."
Dominic West was also at the screening, where he posed for selfies with fans.
He said the UK's current political climate was "dire" but, like the film's ever-positive Dory, he was keeping optimistic.
"I obviously don't like what's happened, but as everybody says we go on and maybe the chaos will throw up something good," he said.
"Hopefully it will throw up something good and hopefully we won't throw up lots of bad things, like far-right groups."
Finding Dory opens in UK cinemas on July 29.
