This Video of Meghan Markle and Kate Middleton Cracking Up at the Queen's Event Is BFF #Goals

Meghan Markle and Kate Middleton just put all those rumors of dueling duchesses to rest in the best way.

Markle, Prince Harry, Middleton and Prince William had their first joint engagement of the year at Prince Charles’s 50th Investiture Anniversary celebration at Buckingham Palace on Tuesday, and it's the first time since Christmas that the Fab Four were reunited publicly.

The two duchesses weren't photographed together at the event, but they were caught on camera giggling to themselves (and we want in on this friendship).

At minute mark 1:47 in the video below, you can see Middleton turn around to Markle before the two sisters-in-law start cracking up. Bets on whether the duchesses were giggling about Prince Harry's dad jokes?

Markle, who is seven months pregnant, wore a metallic silver-and-gold brocade shift under a white coat by Amanda Wakeley (worn three weeks ago for her date night with Prince Harry at the Natural History Museum).

Middleton wore what appears to be a light robin’s egg blue (perhaps pastel green?) dress with midi-length hem and high neckline, reportedly by a private dressmaker. She carried a matching clutch and donned a pair of cream heels.

We’ll next see the Fab Four reunited again for Commonwealth Day, which is set to take place on March 11 at Westminster Abbey to celebrate the Commonwealth of Nations under Her Majesty the Queen.

So will we be getting more Meghan and Kate BFF moments in the Abbey? Fingers crossed.

"Psst, Kate! Wanna get tea and crumpets after this?" Megs will (probably) whisper.
