Clearly in fine form, Jessica is well known for being a dedicated gym bunny, and even she admits she is 'boring' as she keeps to a strict routine.
The actress is in Puerto Rico with her fiancé Justin Timberlake, 31, who's in town with the crew of his new movie, Runner, Runner.
To get a stunning physique like Jessica's does of course involve a lot of sacrifice the actress told ELLE magazine last year. She probably wouldn't be top of your list for a wild night out.

'For me, getting enough sleep, drinking lots of water, having a healthy diet, and staying away from alcohol are musts.
'It's so boring, I know, but doing those things really helps,' she told ELLE.
The actress is also a fan of boxing, martial arts and yoga. "Yoga is a constant for me because it keeps my muscles long and flexible," she explained.
'But now that summer's coming around, I'm planning on spending more time outdoors playing volleyball and jogging with my dog, Tina.'
The actress also maintains a healthy, balanced diet, frequenting places like Real Food Daily, which specializes in organic vegan cuisine.
