He's become one of the Duchess of Sussex's most loyal friends and outspoken cheerleaders, so Daniel Martin caused intrigue when he deleted a video yesterday that he had posted online about his trip to France with her.
The make-up artist had used the video to explain how he had achieved her look for the Balenciaga show at Paris Fashion Week which the former actress attended in support of the brand's latest creative director, Pierpaolo Piccioli.
Martin claimed that his work had 'made her look even more juicy and glowy'.
He added: 'We just wanted to keep everything light, fresh, and radiant,' he gushed. 'She just flew in, and your skin gets dehydrated from the plane, so I just wanted to bring some hydration back into her skin and just bring some life to it.'
He concluded, 'I would love to get her in a lip one day, Meghan if you're watching this, let's do a lip, I'd love to see you in a lip.'
Martin's deletion of the post caused speculation that the duchess may not have been pleased with what he had said.
However, a source tells me it was deleted because Martin had not included all the beauty products which had been used. The source says an updated version of the video is likely to be posted at a later date.
Martin appeared with Prince Harry's wife in the first episode of her Netflix series With Love, Meghan. He later took to social media to attack critics in the most personal way.
One Instagram user, Maria Sampson, a London-based fashion design student, commented on an article about the first episode, in which Meghan prepared bath salts for Martin's stay at her home.
'It's got to the point where you just have to laugh now,' Sampson remarked.
At this, Martin, who prepared Meghan before her royal wedding, took grave offence. In response, he mocked Ms Sampson's fashion designs, which she displays on her Instagram page.
'Like your 'designs'??' he jeered, adding that Ms Sampson didn't have the status to dare comment on Meghan's handiwork.
'Don't come for my friend without receipts...' he warned, melodramatically.
Martin, who has been employed by Meghan since he did the American actress's make-up on legal television drama Suits, did not confine his extraordinary efforts to defend and celebrate her to just one form of social media.
On Threads, he responded to a random question about who was responsible for the music used in With Love, Meghan. 'It's all Meghan!' Martin declared. 'She's the superstar DJ.'
