Hollywood couple Ashton Kutcher and Demi Moore are back in Israel.
It is the second trip to the country in three months for Mr Kutcher.
The pair, who are followers of Kabbalah, have been the subject of rumours about his alleged infidelity and the breakdown of their marriage.
But Mr Kutcher, who has nearly six million followers on his Twitter account, said on Twitter: “Sharing Love & Light while in Israel.”
He said he was “asking [for] the energy [to] forge bonds with our similarities and find compromise in our differences.”
Mr Kutcher, known for the film Dude Where’s My Car?, is in Israel for a communications conference. He spoke at the annual Bezeq Expo on the subject of how to market Israel.
He said: “The first thing you need to decide is who do you want to influence and what do you want to say to them.”
He added that Israel must have “open, candid conversations about what Israel is and who it is, because the people here are amazing.
“The entrepreneurs here are incredible.”
Later Mr Kutcher wrote on Twitter that he was “rocking out” at the conference. He said: “Love getting a glimpse of the future.”
He also praised Israeli entrepreneur Shai Agassi’s clean-transport business, Better Place, and called it “is one of the smartest companies I've ever seen.”
Mr Kutcher married Demi Moore, star of Ghost in 2005 in a Kabbalah ceremony.
Ms Moore, who has more than three million Twitter followers, tweeted that it was “a glorious day here in Israel.”
Following the conference, she said she hoped that the US involves itself in Better Place and called it “a system that could change the world, our dependency on oil and the quality of our planet!
