She is set to give birth to her fourth child in a matter of weeks
But that didn't stop Petra Ecclestone, 31, from throwing a lavish birthday bash for her daughters seventh birthday on Saturday.
Ahead of the event, her sister Tamara posted a series of snaps to Instagram showcasing her daughter's excitement for her Lavinia's LOL themed birthday party.

Dressed in costume, and resembling the brightly coloured LOL doll, five-year-old Sophia posed for a series of snaps in front of a elaborate floral arrangement and decorative pink bathtub.
Donning multicoloured hair and pink fashionable frames, Sophia channeled her best Bon Bon as she smiled gleefully before jumping in beside her mum.
On one of the photos, Tamara captioned the photo: 'Ready to celebrate her cousin LOL style. My real life doll,' followed by a heart-eye emoji.

Meanwhile, the Formula 1 heiress looked effortlessly chic wearing a complete beige ensemble as she prepared for an afternoon of family fun.
Upon arriving at the birthday bash, Tamara shared a series of snapshots from the birthday party, which displayed an edible pancake art station for the kids as well as a giant LOL themed pinata.
Sophia went to town on beating it with a stick, in hope to bust open the cardboard vessel, but proving too much for the real life doll, she threw the stick aside and ripped it open with her hands.
