It's hard to believe that once upon a time Nicole Richie has had two little people growing inside that tummy of hers.
No wonder the mum-of-two wasn't shy about showing off her rock hard abs and toned tum in this snap of her catching some rays.
Looking cool as a cucumber in a coral bikini and a pair of aviator shades, the 'Simple Life' star took some time out from her schedule to relax poolside in LA.
The 31-year-old former reality star has a daughter, Harlow Winter Kate, 5, and a son, Sparrow James Midnight, 4, with her husband, Good Charlotte singer Joel Madden.
It's a busy time for the former reality star. As well as working on charity and environmental projects she's starring in a new online reality series, '#CandidlyNicole'.
