If looks are any indication – and when you look this good, they surely are – Nicole Richie
is in the best shape she's been in years.
Spotted this week in her hotel pool in Miami's South Beach, the 30-year-old beauty – and mother of two
and Fashion Star mentor
– was the picture of health.
Back in 2006, as friends and family expressed their worry, PEOPLE was reporting on the 5'2 Richie's shrinking weight
, and how she sought help
for her issues, also blaming her being thin on "nerves."
Later, she was eating healthier
In 2010, she made it clear she never said
she had an eating disorder, telling the U.K.'s Marie Claire
, "I felt it was a little unfair to say someone has an eating disorder when they don't."
