Viewers of the Essex show know how important Gemma and Bobby are to each other and, although they've had their fair share of dramas in the past, they're always there for each other.
Gemma said: "Bobby and I have been through our many ups and downs but we always come out of everything better friends and he says I'm like the sister he's never had. He's very special to me."
The reality star said one of her big regrets was falling out with Bobby in the past, naming Christmas two years as a particularly difficult time.
Bobby, meanwhile, said something similar about Gemma, saying although they can get very angry at each other, they'll always love each other.
"Deep down she is my bestie, but when we row, we row hammer and tong!" he said.
