Tamara Ecclestone survived on sliced bread at the start of her pregnancy.
The Formula One heiress - who is expecting her first child with former stockbroker Jay Rutland - admits she felt so nauseous during the first few months of her pregnancy she couldn't eat anything except for plain white bread after developing an aversion to all of her favourite foods.
Speaking at the launch party for the Kardashian Kollection for Lipsy at London's Natural History Museum last night (14.11.13), Tamara exclusively told BANG Showbiz: "It's going really well. I was sick lots in the beginning, but I'm good now. I'm a bit tired but generally excited and can't wait now. I'm over halfway.
"I haven't craved anything at all! I've had loads of aversions but no cravings. It's so weird, I can't eat anything I used to like. My taste is kind of coming back. In the beginning I was just surviving on plain bread, but now I'm eating more and more things."
The 29-year-old beauty has been spending as much time as possible with her younger sister, Petra, and her nine-month-old daughter, Lavinia, in order to pick up childcare tips.
She said: "Petra's such an amazing mum. Having her go through it so recently, I'm getting loads of tips from her, she's really helping me out and giving me loads of advice, which is really nice."
The star also confessed she and Jay have decided to keep the baby's sex a secret from their families until the birth.
She gushed, "I'm so excited for this next phase. I know and Jay knows, but that's it. It's a secret! I think he will make the best dad ever."
Tamara was joined by the cast of TV show 'Made in Chelsea', girl band Stooshe and Khloe Kardashain at the star-studded Kardashian Kollection for Lipsy event.
The Kardashian Kollection for Lipsy is available now at Lipsy stores nationwide and online at Lipsy.co.uk
