Kristen Wiig is ''happier than ever'' thanks to Fabrizio Moretti.

The 'Bridesmaids' actress is besotted with The Strokes drummer and has revealed her boyfriend of one year completes her life.

Kristen told Marie Claire magazine: ''I will say that I'm happier than I've ever been. And I feel very lucky right now.

''Where I am now. Who he is. Those are the two big ones.''

Despite her career success, the 38-year-old star knows her personal life and relationships with the people around her will always be more important than her working achievements.

She said: ''When you're on your deathbed you probably aren't counting the movies you've made. You're looking at the people who are around you and thinking about the people in your life, and you can't lose how important that is because that's ultimately where happiness comes from.''

The comedienne left popular sketch show 'Saturday Night Live' in May after seven years as a regular, but has no regrets about her decision.

She explained: ''I know a lot of people probably assume, 'Oh, she's leaving because she is going to be doing movies now and things like that,' which I will be.

''I think maybe if I were 22, I could see myself staying a little bit, but it just felt like the right time.''

Kristen's upcoming film projects include 'The Secret Life of Walter Mitty' with Ben Stiller and 'The Comedian' alongside Robert De Niro.
