'I’m crazy about smoothies, so I bring fruit chopped up and ready to go,' she explained.
'That way, I can sip the same smoothie all morning long between takes. If it thins out, I put it back in the blender with crushed ice for a few minutes.'
The 32-year-old is now pregnant with her second child, and has relaxed her adherance to the Weight Watchers plan until after the birth.

But she will remain the face of the company and they will continue to run ads promoting the blonde's 50lb weight loss, as well as pushing a new commercial in which she announces her pregnancy.  
Praising her 'successful' weight loss, the company added: 'Jessica will not be following the programme during the pregnancy while her weight and well-being are monitored by her obstetrician.'
