The Formula One heiress, who exclusively revealed to HELLO! that she was pregnant with a "honeymoon baby" last month, stepped out to attend an art fair preview in London with a friend.
Dressed in a fitted long-sleeved black polo and speckled black and white skirt, no-one would guess that Tamara, 29, isn’t too far from the half-way mark in her pregnancy. Black high-heeled ankle boots completed her sleek outfit.

While the mum-to-be is keeping her baby bump under wraps, she is showing no signs of playing down her social life.
On Tuesday Tamara head out for a date night with her husband Jay Rutland.
The pair, who wed five months ago in a romantic ceremony in France, attended a party hosted by Sotheby's in the British capital.
The model showed off her curves in a figure-hugging LBD with a low-cut neckline and full skirt that defined her still-small waist and showed off her toned, tanned legs.
Her chic outfit was completed by a pair of Louboutin ankle boots.
Her husband, meanwhile, was dashing in a three-piece suit and tie, as he protectively held an arm around his wife's waist.
"I just feel so lucky," Tamara recently opened up to HELLO! in an exclusive interview.
"I never imagined this all happening so quickly. It's crazy how life works in such mysterious ways. Jay loves children and I'm really excited for the next phase of our relationship."
The delighted father-to-be, 32, told the magazine: "It's been an amazing year, meeting and marrying my beautiful wife. Now we are expecting our first child and looking forward to the next step in our future together."
