Petra Stunt shows off her trim figure in leggings as she hits the spa with one of her four-month-old twin boys
She welcomed her twin boys in April.
And four months on from the birth, Petra Stunt seems be taking to life as a mother of three like a duck to water.
The 26-year-old stopped by a London spa on Tuesday with one of her newborns for a bit of me-time, showing off her trim post-baby figure in figure-hugging work-out clothes.

Busy mum: Petra Stunt emerged from a London spa on Tuesday with one of her newborn twin sons
Petra, 26, teamed a pair of cropped leggings with Nike trainers and a zip-up black top as she emerged from the spa near her home.
Her long blonde hair was left loose and wavy, with the Formula 1 heiress glamming her look up with a touch of makeup.
The doting mum, who also has two-year-old daughter Lavinia, carried one of her sons to her waiting car after her appointment.

Last week Petra and her billionaire husband of four years James marked their boys' christening with a service at St Peter's Church in central London.
The couple were joined by their family and friends for the celebration, with Petra's sister Tamara arriving with her adorable daughter Sophia.
While Tamara is happy to publicise her life with her husband Jay Rutland and little Sophia on social media, her sister Petra is notoriously private and has yet to reveal the names of her twin boys.

Petra and her husband James, 33, married in a spectacular £12million ceremony in a medieval castle near Rome in 2011.
The lavish affair included live performances from the likes of David Guetta and the Black Eyed Peas.
The pair had previously met on a blind date in 2006.
