Meghan Markle lets slip adorable nickname for Prince Harry

At one point during her interview with Serena, Prince Harry can be heard in the background. When she spots her husband, Meghan beckons him over to join them for a moment.

"Hi! You wanna come say hi?" she says, "Look who just popped in!"

Grand Slam champion Serena then adds: "Hello! Hello there!"

Further from the mic, Harry is heard asking Serena: "How you doing?" to which she replies: "Good, how are you?"

The prince then tells her: "I like what you've done with your hair. It's a great vibe" - spoken like a true former royal.

When the quick catch-up comes to an end, Harry heads off, telling Serena and Meghan he hopes they have fun - which is when Meghan reveals the pet name she uses for her husband.

The duchess-turner-podcaster called back to him: "Thanks, my love!"

Elsewhere in episode one of her podcast, Meghan revealed the unfortunate news that her son Archie had been involved in a fire.

Recalling the shocking incident, Meghan explained it had happened when she and Harry were still senior members of the Royal Family and were on their tour of South Africa while Archie, who was just four and a half months old at the time, was put in the care of a nanny.

The couple dropped little Archie off at this housing unit they had been staying at and 'he was getting ready to go down for his nap'.

The couple went out that evening to give a speech, before they returned to some terrifying news from their nanny, Lauren.

"There's been a fire at the residence," Meghan recalled being told. "There's been a fire in the baby's room.

"Our amazing nanny Lauren was in floods of tears. She was supposed to put Archie down for his nap and she just said, 'you know what, let me go and get a snack from downstairs'."

Meghan continued: "In that amount of time that she went downstairs, the heater in the nursery caught on fire. There was no smoke detector, someone just happened to smell smoke down the hallway so they went in and the fire was extinguished.

"He was meant to be sleeping in there."

Discussing the traumatic incident, Meghan revealed that she and Harry were then left with no choice but to go out and attend another official engagement as part of their tour.
