The Rugby player also admitted that he had no plans to marry the 40 year old professional dancer.
Ben, who met Kristina in 2013 when he appeared on Strictly Come Dancing, told The Sun: “No more kids and we’re not talking marriage either.”
The couple share daughter Milena, and Ben also has twin daughters from his previous marriage to childhood sweetheart Abby.
“There are always rumours, but we’re not talking anything like that,” he continued. “We haven’t really mentioned it. We’re happy as we are with three kids.”
But Kristina recently gave a different perspective about her future with the hunk.
Speaking earlier this month, she said she’d love to expand her family again.

“Marriage and another baby is some time in the future – we both like to take it one step at a time,” she said.
“We’re Virgos, we focus on one thing and execute it in the best possible way.”
The blonde bombshell is soon to be returning to the dance floor in a new two-month tour Dance To The Music with fellow former Strictly pro Robin Windsor.
“It’s a lot of pressure on [Ben] to look after the kids but he’s very supportive of me,” she said of being away from her family.
She added how hard she would find it being away from her daughter, nicknamed Mila, saying: “Other mums have to go out and work so I’m no different.
“I’m very lucky to be able to have so much time off and spend the time with Mila. I want to create some legacy and hopefully something Mila will be proud of when she’s older.”
