"I think Cheryl looks great. It's the industry though - everyone gets stick but you can't judge somebody by how they look," he continues.
The reality TV star says he's since avoided reading about himself in the press. "It's usually all negative so I try and keep out of the way of it," Jake adds.

Reggie 'n' Bollie compete against Louisa Johnson and Che Chesterman in this weekend's final.
