nicole richie getty Nicole Richie turns 30; 'Simple Life' star puts complex life behind herReality star, designer, mother of two and rocker wife Nicole Richie celebrated her 30th birthday Wednesday (Sept. 21). And apparently is was a popular one.

She writes to her 2 million Twitter followers, “I can’t believe the outpour of birthday love I am getting on twitter today! From the bottom of my heart (& the top), THANK YOU SO MUCH!”

The star of “The Simple Life” is probably hoping her 30s are simpler than her 20s. That was a period of weight issues, drug arrests, DUI charges and a very short (82 minutes to be exact) jail sentence.

Since then, Richie has cleaned up her act. She married Good Charlotte singer Joel Madden and no doubt spends much of her energy raising their children Sparrow and Harlow. Richie will soon be back in show business as a celebrity mentor on the upcoming NBC reality show “Fashion Star.

Here’s hoping her birthday was “easy like Sunday morning.”
