The three princes got all dressed up for the big premiere.

It was a father-son night out for these three princes!

On Thursday evening, Prince Charles joined his two sons, Prince William and Prince Harry, at the premiere of Our Planet at the Natural History Museum in London, England. The trio looked very dapper in their tuxedos and posed for photos in front of the steps of the venue with acclaimed natural historian Sir David Attenborough, who narrated the eight-part documentary series for Netflix.

While inside the event, the royals were photographed mingling with guests, and William was even spotted having a laugh with former pro soccer player David Beckham.

Harry also shared a photo from the event on his and wife Meghan Markle's new Instagram account. In addition, the post included pics from his trip to Africa with Meghan.

"The Duke of Sussex attends the Our Planet premiere at the Natural History Museum with The Prince of Wales and The Duke of Cambridge, lending their joint support for the protection of our environment," reads the caption.

The royal family is anxiously awaiting the birth of Harry and Meghan's first child. The 34-year-old prince's outing with his 70-year-old father and 36-year-old brother came just hours after news broke that he and his wife had officially moved out of Kensington Palace and into the Frogmore Cottage.

A royal source tells ET that the home was gifted to the parents-to-be by Harry's grandmother, Queen Elizabeth II, and is "a stone's throw" from Windsor Castle, where the couple are expected to spend Easter Sunday.

Harry and Meghan are most excited to be a little bit farther away from all the fanfare. 

"[They] are keen that their child will be able to enjoy their privacy away from the goldfish bowl," the source says. "Harry's attention is completely absorbed with the birth of his first child. He can't wait to become a father. He's been doing everything he can to put Meghan at ease."
