Ashton Kutcher prefers to declare his love for Demi Moore online

The 32-year-old actor — who wed the 48-year-old actress in September 2005 — thinks using social networking websites to send affectionate messages to his spouse is no different to sending flowers to the workplace.

“Sending sweet nothings on twitter or Facebook is fun,” he said. “In some ways, it’s no different than sending flowers to the office: You are declaring your love for everyone to see. Who doesn’t like to be publicly adored?”

However Ashton — who is renowned for his love of social media and has admitted to tweeting his wife even when she is sitting beside him — has warned people to be careful of what they post online.

“Just remember that what you post is out there and there’s some stuff you can’t unsee,” he said.

Although Ashton loves to declare his affection for wife Demi online, he does admit a computer is no substitute for human contact.

“When someone needs us, he or she needs all of us. There’s no text that can replace a loving touch when someone we love is hurting,” he said.
