After turning 40 and giving birth to her third child last year, Julia Roberts could be forgiven for letting herself go a bit.
Despite stepping out of the limelight in recent years to raise her family, Roberts still has her Hollywood figure if these shots are anything to go by.
The Oscar winner brought three-year-old twins Hazel and Phinnaeus and one-year-old Henry for a family holiday in Hawaii.

Dressed in a black and pink bikini, Julia looked healthy and toned as she strolled around the hotel complex.
Although supported by a group of assistants and nannies, the actress showed she was a hands-on mum and happily frolicked in the pool with her young offspring.
Missing out on the sun-fuelled fun was Julia's cinematographer husband Daniel Moder, who is currently putting the finishing touches to the couple's new film Fireflies In The Garden.

As Julia played in the pool with her children, she displayed her famous smile to fellow holidaymakers.
Julia recently came top of a poll by online bank Smile for having the most genuine celebrity smile.
In second place was X Factor judge Simon Cowell and Ugly Betty actress America Ferreira in third place.
It will be back to work for Julia in two weeks when she travels to New York City to introduce her favourite group Dave Matthews Band at the Stand Up for a Cure 2008 charity concert on September 10.
