Tamara Ecclestone has shared the first pictures of her newborn baby girl, one month after giving birth.
Tamara, 34, confirmed the birth of her and Jay Rutland's second daughter, who they have called Serena, earlier this month.
They already share six-year-old Sophia.
The Formula 1 heiress took to her Instagram Stories on Tuesday to share gorgeous snaps of her new daughter.
The mum-of-two beamed at the camera as she cradled her baby while out on an autumnal walk.
The socialite looked glam as ever as she kept warm in a gorgeous beige wool hat and jumper while going make-up free.
She accessorised with square-framed sunglasses with little Serena cuddled in close in a baby carrier.
Meanwhile businessman Jay, 39, also uploaded gorgeous snaps of their eldest child Sophia snuggling her younger sister.
She was pictured sat on a lavish bed in her pyjamas while holding her baby sister in her arms in a sweet moment.
Tamara and Jay shared the news of Serena’s birth earlier this month with a snap of Sophia, who they affectionately call Fifi, cradling her baby sister.
Tamara's father Bernie had previously shared the happy news of Serena's birth.
Both parents shared the snap, Tamara writing: "Three weeks ago you completed us baby Serena.
"Watching the love Fifi has for her baby sister makes me happier and prouder then I could of ever dreamed of.”
Jay shared the caption: "It's all love."
Tamara gave birth in a Swiss hospital in the country's capital, Bern, in mid-September.
Her father, Formula 1 mogul and businessman Bernie, previously told MailOnline a week after the birth: "I'm absolutely thrilled to be a grandfather again.
"Tamara gave birth to a little girl seven days ago in the same hospital that my son Ace was born in. Mother and baby are doing brilliantly. She's a beautiful little thing.
"She has named her Serena and both of them have been already out on the town together around Gstaad.
"Serena and Ace are very close in age and so will be able to play together when they're a little older.
"I'm delighted that Serena is with us at last. I'm getting quite the collection of grandkids!"
Tamara revealed last year that the couple were trying for baby number two.
She told Hello! that Fifi had also been telling her parents how much she wanted a baby sister.
"She's been talking about how much she wants a sibling," Tamara shared, "and for the first time I'm open to the idea.
"She really wants a sister, but certainly not a brother - she's very girlie and thinks boys are smelly.
"Having another baby is obviously scary because it would mean a big change, but I'm definitely up for it."
Tamara and Jay wed in 2013 after a whirlwind one-month romance.
