Petra Ecclestone becomes a mother of four as she gives birth to a baby girl

Petra Ecclestone has given birth to a baby girl, her fiancé Sam Palmer revealed on Instagram on Sunday afternoon.

The 31-year-old heiress’ fiance took to his Instagram Stories to make the announcement, revealing that they welcomed their child into the world last month.

His message read: ‘I have received lots of messages asking when the baby is due. We had a beautiful daughter a few weeks ago.

Joyful: Petra Ecclestone, 31, has welcomed her first child with fiancé Sam Palmer after her sister Tamara, 35, confirmed she was expecting a baby in November last year

‘Thanks for all the messages. Mother and daughter are both very well. She is yet to see the world, but I’ve told her she will one day if she behaves.’

Petra’s sister Tamara, 35, confirmed she was expecting a baby in November last year.

The blonde beauty is already mother to three other children, Lavinia, 11, and twin boys James and Robert, both four, from her marriage to ex-husband James Stunt.

Last month Petra celebrated her pregnancy with a pink Minnie Mouse themed baby shower, where she sported a pair of mouse ears and a butterfly print dress. 

The Formula 1 heiress looked radiant in a pink gown – complemented with Minnie Mouse ears – as she arrived at the celebratory event thrown by her sister Tamara, who arrived with her daughter Sophia, five.

As the proceedings wound to a close, Tamara took to Instagram to share a series of snapshots from the baby shower, which displayed the pink colour scheme.

Guests were also treated to a healthy supply of champagne as they toasted the baby’s imminent arrival.

The couple announced their engagement on New Year’s Eve 2018 – just over a year after her break-up with businessman James.

Their divorce was finalised in October 2017, after six years of marriage. Recruitment consultant Sam is the best friend of Tamara’s husband Jay Rutland, 38.

Petra previously said of their meeting: ‘It was so unexpected. I ­randomly bumped into him when he came to LA to visit Jay. 

‘I honestly thought I was going to turn celibate, or into a lesbian. You meet someone when you least expect it or when you don’t want it… that’s always when it happens.
