"During my pregnancy, it's been my favourite thing to come home at whatever time of day and change into my PJs," says Tamara. "The first thing I do is shower, scrub my face and massages loads of oil into my skin to prevent stretch marks.
"I haven't bought any maternity clothes," adds the glamorous 29-year old. "I just wear my stretchy garments or buy the next size up. I've been lucky because I've not grown that big. All my rings still fit and I can wear my heels."
Showing how confident she is in her body, she has posed in a 'Demi Moore' style shoot for HELLO! with the birth of her little girl now nearly upon her.
She tells the magazine: "It might sound crazy, but I feel in tune with my baby and talk to her all the time. I know she can hear me, so she'll definitely recognise my voice when she's born.
"I keep having dreams about her, too. In one, she had straight blonde hair and was tiny. She wasn't crying: she was calm and content. It's strange to dream about someone you haven't yet me, but I'm so looking forward to the real thing."
One of the first people she called when she heard she was expecting a girl with businessman Jay Rutland, was her dad F1 supremo Bernie Ecclestone.
"Dad said 'of course, another girl in the family. More handbags! He loves kids." See the full interview in HELLO! out now.
