London, June 20 (IANS) Singer Robbie Williams says he would like to adopt two orphans sometime in the future.

The singer recently visited Haiti on charity efforts and felt 'guilt' at not being able to rescue countless children without homes and parents in the earthquake-stricken country.

'I wanted to adopt straight away. That's the instant guilt thing you get when you first get to somewhere like that. But I've got a few things I want to do before that happens. I'll probably have a couple of my own first and then I'd like to adopt a couple too,' he told the Sunday Mirror.

The 36-year-old, who is dating actress Ayda Field, added: 'It's something we've talked about. I think it's on the horizon but I don't know when.'
