Graham Campbell thinks Kaia Gerber is a "real artist". The actor stars alongside Kaia, 24, in The Shards, the new teen thriller series, and Graham has heaped praise on his co-star. Graham, 24, told People: "Kaia has a wild intelligence that I think the world knows quite a bit about, especially through her work with her company Library Science [Kaia's book club]. I was like, ‘That is a real artist, a person with a real artist’s soul.’ Kaia also remembered being impressed by Graham and she's thrilled that they're now starring together in The Shards.
