Dianna Agron has never been "happier".

The 25-year-old actress - who is currently dating 'Gossip Girl' star Sebastian Stan after breaking up with British hunk Alex Pettyfer earlier this year - loves the direction her life is taking and is enjoying getting older.

She said: "I'm the happiest that I've ever been. Ever. High school, middle school-I've loved every part of getting older and growing, but I definitely think that this is the most I've ever felt like myself and that I'm being treated like who I feel I am."

However, the blonde beauty, who is best known for her character Quinn Fabray in musical TV show 'Glee', also revealed she regularly thinks about the direction her life may have taken had she made different decisions earlier in her life.

She added to Flaunt magazine: "If this was six years ago, what would I be doing in the exact same place or situation? It's something that, when I write, it could be a situation or a person that is similar to something that I know, but I go in a completely different direction with it, based off of one Small Change."
