The 39-year-old singer and wife Ayda Field welcomed their first child, daughter Theodora Rose, recently and while Williams is smitten with the tot, he thinks the feeling isn't always mutual, reported Daily Star.
"She's not interested in peek-aboo. She's a tough audience these days. I think it's because her teeth are coming through, or she just thinks I'm not funny - but that's showbiz. I need to slip her a pint I think," he said.
The singer recently wrote a song called 'Go Gentle' for his daughter but she wasn't too impressed by her father's singing.
