A new royal family portrait has been released by Buckingham Palace – and it's giving royal watchers a rare look at baby Prince Louis!

The photo was released in celebration of Prince Charles' 70th birthday, which is Wednesday.

In the photo, Charles sits alongside Duchess Camilla, with Prince William, Duchess Kate, Prince George, Princess Charlotte, Prince Louis, Prince Harry and Duchess Meghan gathered around them.

George, who appears to have had a growth spurt in recent weeks, sits on his grandfather Charles' lap while Charlotte sits next to Camilla. Young Louis is held in Kate's arms.

In a second photo, the family poses in the same spot with more candid expressions.

George, 5, has a big smile on his face, Camilla appears to point at the photographer and Meghan is doubled over in laughter.

The photos were taken by Chris Jackson in the garden at Clarence House in London on Sept. 5.

In a press release, Jackson said he was "delighted" to have been asked to take the portraits for the important birthday milestone.

"It was particularly special to capture such an informal and relaxed family portrait over a fun afternoon in the gardens of Clarence House," he added.
