Meghan Markle sparkled on the red carpet with Prince Harry as they attended the premiere of The Lion King.
The Duke and Duchess of Sussex looked a picture of happiness as they arrived holding hands to the tune of Can You Feel the Love Tonight.
They were also met with a chorus of cheers and shrieks from the throngs of people gathered in Leicester Square, London.
Meghan, 37, stunned in a chic Sh450, 000 (£3,500) black knee-length flared dress with sheer sleeves and neckline from the Jason Wu Collection.
She teamed it with a black Gucci clutch and Aquazzura heels and styled her hair in a sleek bun.
The former actress, who is on maternity leave, chatted and waved at the crowds and at one point was in fits of giggles.
While Harry, 34, looked dapper in a suit with a bow tie.
The pair, who welcomed son Archie in May, spent the evening mingling with A-Listers, including Beyoncé and Donald Glover (Childish Gambino) who star in the updated Disney classic.
The photorealistic computer-animated remake of the beloved 1994 film boasts a star-studded cast, including Glover as king-in-waiting Simba and Beyoncé voicing his love interest Nala.
Sir Elton John, who helped create music for the original film, was also among the big names attending tonight.
While Pharrell Williams, Rochelle and Marvin Humes, Myleene Klass and actor Seth Rogen were some of the other celebs at the glitzy bash.
Harry and Meghan attended the event in aid of conservation work through The Royal Foundation.
Buckingham Palace said: "The Duke of Sussex has taken a deep personal interest in frontline conservation projects that work to protect Africa's natural heritage and support both wildlife and local communities."
The pair are taking baby Archie to South Africa in the autumn.
The Duke is also carrying out solo visits to Angola, Malawi and Botswana.
Last night, they met some of the cast and crew before watching the film, which will be released on July 19.
The duo was then expected to speak to representatives from organisations working to protect wildlife and the environment.
For the film's release, Disney announced the Protect the Pride campaign, aimed at raising awareness of dwindling lion numbers.
The Royal Foundation will be involved with and support the campaign.
Meanwhile, Beyoncé and the Duchess looked thrilled to see each other ahead of the screening, as they shared a hug and talked baby Archie.
The pair couldn't hide their excitement and embraced before Beyoncé gushed: "We love you guys."
The singing sensation, dressed in a daring yellow evening gown split to the thigh, also commented on how "beautiful" Archie is as they exchanged parenting tips.
"The baby’s, so beautiful," cooed Beyoncé. "We love you guys."
When Beyoncé won a Brit Award with her husband, rapper Jay Z, they paid tribute to Meghan.
Unable to attend the awards ceremony, the couple - who go by The Carters for their collaborations - sent a video acceptance speech.
In it, they stood in front of a Mona Lisa replica, with Meghan in the frame instead of the famous Leonardo da Vinci figure.
Beyoncé posted a picture of the scene on her official Instagram account, with the caption: “In honour of Black History Month, we bow down to one of our Melanated Monas.
“Congrats on your pregnancy! We wish you so much joy.”
The phrase 'Melanated Monas' was a reference to the Duchess of Sussex's biracial heritage.
Beyoncé and Jay Z - had been due to walk the yellow carpet, appropriately spotted with paw-prints, before the royal guests.
But the couple was running late, while Harry and Meghan were five minutes early.
So as the royals walked to the entrance of the cinema greeting fans, Beyoncé and Jay-Z were forced to make a hasty arrival via a side entrance in order to be in position for the meet and greet, to the disappointment of some fans.
Meanwhile, Harry greeted Sir Elton warmly with a huge hug.
The prince has known the singer for most of his life and his late mother, Diana, Princess of Wales, was a close friend.
Meghan also hugged the star, who she met when he sang at her and Harry's wedding.
Sir Eton was in awe of Meghan’s black stilettos which had a pretty diamanté strap at the back.
"I’m admiring your shoes," he said, looking down at them, prompting a smile from Meghan.
"Yours is pretty nice too," interjected Bob Iger, chairman and chief executive officer of Walt Disney.
"It’s just incredible, you’re in for a great night," said Sir Elton.
