The British funnyman - who filed for divorce in December after just 14 months of marriage - didn`t sign a pre-nuptial agreement with the `Firework` singer so is legally entitled to half her $44 million fortune. However, Russell has told Katy he doesn`t want anything from her and wants their split to be as amicable as possible. According to TMZ.com, their divorce will become official on June 30 because there is a six month waiting period. It was recently reported Russell - who was famed for his womanising ways before he met Katy - had started dating again and was seeing more than one woman. Sources said Katy had been told that her estranged husband - who has previously been treated for sex addiction and substance abuse issues - had moved on from their marriage by her pals. One said: "She discovered through her friends. One of the women told a friend of hers and it got back to Katy."
