Tamara kept her bump covered in a clingy black dress to attend a showing of West End play The Book of Mormom in London alongside husband Jay Rutland.
Tamara added thigh high black boots – but no coat in this chilly weather! – to complete her look.
29-year-old Tamara and husband Jay, 31, were enjoying one of their last weekends together before their first child arrives.
"Lovely weekend with my husband one of the last before our baby comes can't wait," tweeted Tamara.
Their night out started with dinner at Shake Shack ("best dinner," said Tamara) before heading over to the Prince of Wales theatre to catching a showing of Book of Mormon.
"Heard so much about Book of Mormon really looking forward to seeing it tonight," tweeted Tamara, later adding it had been a "perfect" evening.
Formula 1 heiress Tamara and businessman Jay announced their pregnancy in September 2013, after marrying in a lavish ceremony in the French Riviera the previous June. They later made it official with a wedding at the Chelsea Old Town Hall in London.
