Luisa Zissman is six months pregnant

Reality television personality Luisa Zissman, who announced just last week that she's in the family way, has revealed she is six months pregnant.

The former "Apprentice" runner-up announced she and her partner Andrew Collins were expecting their first child together last week, but it seems Zissman is actually closer to her due date than fans initially thought, reports dailymail.co.uk.

Taking to her Instagram account, Zissman, who is currently on holiday, uploaded a photograph of her in a bikini, showing off her bump.

"Last day sunning the bump can't believe I'm 6 months already! #6months #pregnant #bumpwatch (sic)," she captioned the image.

Although she is just about to enter into her third trimester, the 28-year-old star is still battling with cravings.

Uploading an image of her indulging in a delicious chocolate ice-cream while lapping up the sun's warm rays, she wrote: "Ice cream and sunshine indulging my pregnancy cravings #pregnant #icecream #sunshine (sic)."

Zissman, who already has five-year-old daughter Dixie from her first marriage to Oliver Zissman, announced she was expecting another baby on April Fools' Day, which led to fans assuming it was a joke.
