The presenter - who got engaged to the model in March 2009 - stopped drinking altogether once she met Luke and believes he has made her a "better person".

She said: "He's turned me into a better person. He really has. I didn't care before I met Luke. I was out every night, drunk. I didn't have somebody to be a better person for and then that all changed when I met Luke."

The 25-year-old star is now completely teetotal because she doesn't trust how she might behave after she's had a few drinks.

She explained to more! magazine: "I don't drink at all. Even a glass of wine at dinner would probably mean me going home, getting s**t-faced and then being on drugs and doing something stupid that I have to spend the next three months apologising for.
