The 28-year-old star is expecting her second baby with husband Hank Baskett, who she married in 2009, and has completely overhauled her diet during the pregnancy, reported Contactmusic.
"I'm cooking! I've been teaching myself how to cook and using nothing but organic, low fat food. We try to be meat-free as much as we can. I'm drinking green smoothies every day. I crave healthy food like oranges and lemons, potato salad and capers," Wilkinson said.
The 'The Girls Next Door' star, who also has four-year-old son Hank IV - is glad she's having her second child - a baby girl - before she reaches 30.
