Colin Firth's ex-wife has blasted Gwyneth Paltrow as a "nasty person" over her advert for an Israeli property company.

Livia Giuggioli was horrified when she saw Gwyneth's commercial for luxury real estate development 51 park, which is believed to be located just miles from where Palestinians are being killed and displaced, and she took to Instagram to lash out at the Oscar-winner.

She also revealed she was axing a planned visit for Gwyneth to her Italian farm.

Livia fumed: "I just cancelled Gwyneth Paltrow. She was supposed to come to the farm in a couple of weeks' time on a tour, a soil-to-fork farm experience. And we just cancelled her because what she did is completely unacceptable.

"I actually have an appeal for everyone in Hollywood, who for so many years cancelled people who were speaking out about the genocide.

"Even me. I remember being at the Green Fashion Awards [which Livia founded] and I was told by lots of agents that you shouldn't post on Instagram what you do, your activism. And I was like 'f off', of course I'm going to keep speaking.

"Now, I hope the reverse is going to happen - that Hollywood and people in Hollywood are going to start cancelling those who actually support the genocide.

"Because it's not even being silent. There is no excuse for being silent anymore - and many, many people are silent. So let's not even go to the, 'If you're silent, you're complicit argument.'"

She went on to call Gwyneth "complicit" due to the ad.

She said: "She actually actively promoted the genocide, so it's totally complicit.

"Making an ad for a luxury condo is as disgusting as it can be for someone with privilege. It's like how detached are you from reality? You're either so detached that you need to be cancelled, because you live in another world.

Or you're actually a really, really nasty person. Or you are stupid. Which of the three are you, Gwyneth Paltrow? And definitely you are not coming to our farm!"

Colin and Livia split in 2019 after 22 years of marriage. He previously co-starred with Gwyneth in 1998's Shakespeare in Love.
