Prince Harry has made his first public appearance after the announcement that Lilibet had been christened at a home ceremony.
The Duke of Sussex took to the stage and answered questions at BetterUp's Uplift summit on Wednesday night.
He was joined by BetterUp CEO Alexi Robichaux for the live event that took place in San Francisco shortly after 1am UK-time.
They both answered a series of questions about the work of the organisation.
At one point, the Duke quipped that some of the questions that were put to the pair were 'not appropriate.'
It comes after Prince Harry and Meghan Markle's daughter Lilibet was christened last Friday at her home in Montecito, California, with around 20 to 30 people in attendance for the celebration.
Among those at the intimate gathering were said to be Meghan's mother Doria Ragland, Lilibet's godfather Tyler Perry and an unnamed godmother.
A spokesperson for Harry and Meghan said: "I can confirm that Princess Lilibet Diana was christened on Friday, March 3 by the Archbishop of Los Angeles, the Rev John Taylor."
It is the first time she has been publicly referred to as Princess. She became entitled to become a princess when her grandfather King Charles acceded to the throne.
The rules set out by King George V in 1917 mean Harry and Meghan's older son Archie and Lili, as the children of a son of a sovereign, are automatically a prince and a princess and also now have an HRH style if they choose to use it.
Prince Harry is chief impact officer at the Silicon Valley startup that focuses on coaching people on their mental health to help people's performance.
BetterUp offers custom support and services that "strengthen mental fitness", with the aim of allowing customers to "unleash personal and professional performance".
