After weeks of controversy surrounding her privacy demands, the Duchess of Sussex appeared to hint that she's been having a difficult time when she attended The Lion King European premiere on Sunday.

Meghan, 37, met stars of the film at the event in London's Leicester Square alongside Prince Harry, 34, and was seen chatting with Pharrell Williams, 46, who was involved in the Disney movie's soundtrack.

Eagle-eyed royal fan @royal_suitor shared a video of the exchange on Twitter, which showed Pharrell praising Meghan and Harry's 'wonderful union' as 'significant in today's climate'.

The Duchess was heard responding: 'Thank you, they don't make it easy.'

In recent weeks, Meghan and Harry have faced criticism for insisting on keeping their son Archie's christening completely private and refusing to reveal the names of his godparents.

A week later, Meghan made a controversial 'private' appearance at Wimbledon with two friends and caused a stir when bodyguards told fans not to take pictures of her.

The Duke and Duchess met the cast and crew of The Lion King during a line-up inside the Odeon in Leicester Square, including Pharrell Williams.

The exchange began with Harry laughingly admiring Pharrell's tuxedo jacket and shorts combination, and the musician doing a jokey curtsey for the prince.

‘I love the look,’ laughed Harry, pointing to the eccentric outfit.

Royal fan Pharrell took the opportunity to praise the royal couple, telling them:'So happy for your union. Love is amazing. It’s wonderful.'

He added: 'Don’t ever take that for granted, but what it means in today’s climate, I just

wanted to tell you it’s so significant for so many of us. Seriously.'

Meghan thanked the musician, saying: 'That's so kind of you to say.'

Pharrell continued: 'It's significant. I cheer you guys on.'

Reaching out to touch him on the arm, the Duchess admitted: 'They don't make it easy.'

Pharrell added: 'So you understand the significance. It's beautiful.'

The premiere comes at the end of a difficult period for Meghan, who has faced widespread backlash over her privacy demands.
