Harry Styles made Caroline Flack ''harder''.

The 32-year-old TV presenter received a lot of criticism over her three-month romance with the One Direction singer but she has no regrets as she has learned lessons from the experience.

Caroline told LOOK magazine: ''I wouldn't edit anything out of my life. I learnt the hard way that the easiest thing is to keep it to myself, with the whole Harry situation, about 95 per cent of what was written was false.

''I didn't really know where to begin. But I've developed thicker skin and become more hardened to it. I don't get as upset as I used to, but I'm still human.''

The bubbly brunette admits she was ''surprised'' by some of the extreme reactions the 'One Thing' hitmaker's fans had, which included sending her death threats via twitter.

Caroline said: ''I'm surprised - it's tough. I didn't kill someone, I just went out with someone younger, but there have been more positive reactions than negative ones.''

The star has been single since splitting from the tousled-haired teen in January 2012, but insists she isn't looking for a serious relationship.

She said: ''I'm single, happy and dating. I'm not looking for anything, just having fun and if I find a connection with someone then I'll take it from there.''
