Perhaps Halle Berry
could star in a reboot of the old TV classic Sea Hunt
As seen here, the Oscar winner, sporting a blue bikini top and denim daisy dukes that showed off her toned Malibu-tiful beach body to perfection, shared a laugh with friends while searching for seashells on a Malibu beach Sunday.
Berry, 46, certainly has plenty to smile about: Her new movie with Tom Hanks, the much-buzzed-about time-traveling romance Cloud Atlas
, opens in theaters Oct. 26.
So how does the star keep herself so fit? She has help from her trainer Nat Bardonnet
, who tells PEOPLE Berry works out – hard – to stay in such great shape.
"Her abs look amazing," says Bardonnet, who plans 30-minute power workouts with the actress at least three times a week.
The intense cross training sessions – which Berry does while blasting dance music from artists like Ne-Yo or Chris Brown – include everything from push-ups and planks to weight training.
"The way I push Halle, not many people would be able to last," says Bardonnet. "She always has great energy and a great smile."
Adds the trainer, "She always stuns me how beautiful and sexy she looks. Whatever curveball I throw at her, she can take."
