Pippa Middleton, the sister of Kate Middleton, the Duchess of Cambridge, has a secret identity. She apparently uses an alias to protect her privacy when she's calling for a cab ride.

According to Daily Mail, Pippa's alias is Lucy Middleton, which is apparently one of the real names of Kate and Pippa's relative. A taxi driver outed her alter ego and also said that Pippa hid in a dark doorway the whole time she waited for her ride. She apparently kept ringing him up as well to ask if he has arrived.

But the attempt to be incognito made the driver even more curious. So, the driver actually Googled the name and saw photos of Kate, Pippa and their cousin Lucy together. That's where he realized that the woman who sat in his cab was actually Pippa.

The real Lucy Middleton works as a solicitor in London. She is also one of the godparents of Prince Louis, the youngest child of Prince William and Kate.

Pippa, who is a year younger than Kate, lives in Chelsea with her hedge fund manager husband James Matthew and son, Arthur, who turned one in October 2019. Though they join Kate and Prince William on some events, this Middleton-Matthews family are quite low profile.

The Duchess of Cambridge's sister became famous as she stood as Kate's Maid of Honor during her wedding to Prince William in 2011. Pippa was praised for her beautiful form in her simple bridal entourage gown.

Pippa is often seen juggling her mommy duties, her times at the gym, and her various civic duties. She is an ambassador to the British Heart Foundation. She also works as a writer and has published a few books whose proceeds went to her causes.

When she isn't working, Pippa is often spotted walking her son in West London. Arthur's full name is actually Arthur Michael William, after Pippa's father and deceased brother-in-law, who died in a tragic accident in 1999. Pippa and her husband have been running a foundation in Michael Matthew's name to help the impoverished communities in Asia and Africa.

Pippa and her husband, who was formerly a professional racing driver, were engaged in 2016. They got married a year later with Princess Charlotte and Prince George serving as part of the entourage. In June 2018, Pippa and James confirmed that they were expecting their first-born. A few months later, they welcomed their son.

Pippa is an advocate on cranial osteopathy to retune the baby's body. Kate's sister apparently swears by this process to manipulate the head and spine gently after a traumatic birth.
