Looks like Lauren Conrad is thinking pink -- again! Yesterday, the star posted an Instagram of her newly-shorn rosy strands, officially announcing her return to the rainbow hair streak currently running through Hollywood. While Conrad pulled a clever April Fools' joke by pretending to debut a pale purple color, she's no stranger to the pastel hair trend. In the past, she's been peach, blue, hot pink, and even ended up sporting a rosy hue by accident after participating in Holi, the Hindu festival of colors, last year. The star has yet to post a picture of the final result, but if her previous looks are an indicator, we know she'll wear the style well, and we can't help but wonder if she'll keep it for her upcoming wedding. After all, pink is the color of romance!
