You are the most beautiful girl I have ever met in my life.这句是直译,也是比较正常的说法。
如果要再意译的话
I don't believe love until I met you.直到遇见你我才相信爱情。
No girl was beautiful until(before) I met you.在我遇到你之前,我认为全天下的女孩都不好看。
I HAVEN`T SEEN NO GIRL MORE BEAUYTIFUL THAN YOU
you are the most beautiful girl i meet all my life
You are the most beautiful girl that I have ever met
I can not scream out your beauty with words but my life. 呵呵 意译的 望采纳
