The stunning Rebecca Danielle Cole cheered on Cleverly as he fought Badou Jack.
Rebecca, who was a finalist in Miss Great Britain, works as a part-time model and is also a talented artist.
She met the light-heavyweight in a chance encounter set-up by a boxing promoter in 2008.

She previously revealed: “I was chosen as Miss Swindon and a boxing promoter asked me to carry the Welsh flag into the ring before Nathan’s fight.
“Then a month later, he got in touch with me and we just clicked. We’ve been together ever since.”
Rebecca has been at Cleverly’s side, supporting him during and after fights.

And she added that Nathan returned the favour by appearing at her side in Miss Great Britain.
On living with the boxer, she said: “It sounds ridiculous but he needs someone there to make sure he’s up for training, to run him a bath and to make sure he’s eating right, that sort of thing. I know that sounds daft but it’s true.
“Everybody always asks me whether I get nervous watching him fight in the ring and, to be honest, I feel what he feels.”
Even though Nathan crashed to a fifth round stoppage defeat, he is bound to still be going home happy.
