Meghan Markle’s birthday celebration didn’t end with a celebration at home. The Duchess and Prince Harry took a secret post-birthday bash along with baby Archie.

Prince Harry and Meghan Markle reportedly spent their first summer trip on a lowkey vacation to Ibiza just two days after the Duchess of Sussex celebrated her 38th birthday.

The couple flew on a private jet with their son Archie and arrived at the Spanish island on August 6, Daily Star Online reported. According to the report, the royal family returned on Monday.

The trip is infant Archie’s first ever overseas trip.

Even with the reported security entourage they brought with them, it is unknown how the family managed to escape the eyes of the paparazzi in the crowded tourist island.

The destination, on the other hand, is not new to Markle’s fans.

On an Instagram post by Markle’s friend Misha Nonoo, the girls can be seen basking in the Mediterranean sunshine with the Duchess’ childhood friend Benita Litt.

The post by the fashion designer is dated August 2016, a time long before the former “Suits” actress met the prince.

The Duchess celebrated her birthday quietly with Prince Harry and Archie at Frogmore Cottage. Prince Harry left her a short and sweet message with a never-before-seen photo.

“Happy Birthday to my amazing wife. Thank you for joining me on this adventure!” he wrote. “Love, H.”

The “H” signature pays tribute to Markle’s moniker from her transcription days, a simple letter “M” that she still uses in sending emails.

The Duke and Duchess of Cambridge also greeted Markle on her special day through Kensington Palace: “Wishing a very happy birthday to The Duchess of Sussex today!”

Like many of the gestures and actions of Markle, her birthday cake carried a special message.

Lumina Bakery, a bake shop in northeast London that forwards a cause for homeless women and of women empowerment, created Markle with a sweet carrot cake.

The bakery’s cause is championed by Markle and has been included in her guest-edited British Vogue September issue, “Forces of Change”.

"To have someone like the Duchess acknowledge us and champion us is incredible," Williams told Good Morning America. "I think it will open a lot of doors for us. There's so many more women that need opportunities.”

Lumina works at empowering disadvantaged women by enjoining them in a six-month training program for baking skills and necessary life lessons such as building networks and developing trust.
