The 29-year-old,'Dear Darlin' singer got inspired to begin his own family after seeing the happiness of Williams', who has become a father for the very first time, reported Contactmusic.
"Little Teddy is such a little bundle of joy. To see her little face around the place is brilliant and Robbie is so happy. He has a big smile on his face every day," he said.
"I'm definitely broody but then I'm always broody. I'm probably the most sensitive man. I want to have lots of children, eventually," he added.
"It's been a brilliant tour so far and Robbie and me have been having an amazing time. I've actually been a support act a few times now but I've never had an experience like this," he said.
"I've never had so much love from another artist before and it's so nice. Robbie's been a true gent on this tour and I have nothing but utter respect for him. It's great to be able to spend time with someone like him because he's such a laugh," he added.
