Ok, not a 26 year age gap, a 27 year one 
His AliG comments were made in an interview in The Telegraph
When I ask what he spends his money on he rolls his eyes. 'School fees…' He had qualms about it at first, but all his children have been educated at private schools. Where he lives is not exactly the worst part of London, he says, but the local comprehensives were never an option. 'I don't want my kids coming home speaking like Ali G - I'm just not having it.' In addition to Natt and Leah, Weller has a daughter, Dylan, 11, by a short-lived relationship, and a daughter Jessie, six, and son, Mac, with his partner of the past 10 years, Sammi - 12 years his junior - whom Weller met when he was recording at the Manor studios, where she was working
It was published in 2008, shortly before he left Sammi for Hannah who (on checking my facts) was 23 and he was 50. They have indeed had twins and a daughter - born when Paul was 59.
Like I said, a life worthy of many an AIBU thread.
