Razorlight frontman Johnny Borrell insists he's never been happier after splitting from Hollywood beauty Kirsten Dunst. The British rocker dated Kirsten, 24, throughout last summer (07), while the Spiderman star was shooting How to Lose Friends And Alienate People in London. The pair split in August (07) after Dunst was reportedly put off by Borrell's hectic lifestyle and lack of personal hygiene. Now the 27-year-old singer has hit back - insisting he prefers the bachelor lifestyle anyway. He tells British newspaper The Sun, "I couldn't be happier single. I'm enjoying myself. I'm doing lots of running - keeping fit - and loads more gigs with the band. Everything's going really well."
