Janice Dickinson “Pink halterneck Bikini” as she takes her dog for a walk in Malibu

Just last week Janice Dickinson seemed to finally realise that her dress sense was a little inappropriate for her age when she was spotted in a demure ensemble.

Yesterday however the former supermodel rebelled once again and was out to show she's still got it when she was spotted in Malibu.

The 57-year-old was pictured parading on the beach in a pink halterneck bikini as she hung out with her dog Lloyd.

Janice Dickinson tanned “Black Bikini” body on Malibu beach

After a string of bad press, former supermodel and reality star Janice Dickinson threw on a black string bikini for a relaxing Malibu beach day over Memorial Day weekend.

After unflattering photos of her wrinkled legs emerged at last week's American Idol finale, the 57-year-old looked determined to show off the toned and tanned figure that made her 'the world's first supermodel.'

With visibly defined ab muscles, the well-preserved star was seen yesterday playing with her two dogs - a chocolate Labrador and a Bulldog named Lloyd - strolling on the beach, and sunbathing on a sundeck with an older female companion.
