It's not every day that you see John Lennon's sons together.

The half-brothers Julian Lennon, 58, and Sean Ono Lennon, 46, are currently on a road trip in California. The rare reunion has come after they attended the LA premiere of the new Beatles documentary Get Back.

John Lennon's son Julian and Sean reunite on new trip: Photos

Julian, John's son with Cynthia Powell, has been getting especially nostalgic about the family time. He had rave reviews for the new Beatles film, and he's also loving the reunion with his half-brother Sean. "Only Love," he captioned the photo seen below.

Since the screening, Julian and Sean appear to be touring the remarkable scenery around California. Julian, who is a photographer, has been sharing some nature shots, along with this selfie before a breathtaking sunset with his brother.

Lennon wrote of the picture: "A lil wind blown & tired after a few hours driving through the Mountains to the Sea, but so worth it…. A Magical Day."

Nice to see the Lennon brothers together again! Julian lives in Monaco while Sean, John's son with Yoko Ono, lives in the US, so they're rarely spotted out and about together.
