"Growing up with my family gave me some of my best memories," she told the Daily Mail. "I'd like to have a family of my own - slip away for a bit and do nothing but spend those early years with my children.
"It's about wanting a family rather than wanting a career. I'd like to think I can come back, but I believe children are a gift and I want to enjoy them some time in the next few years. Gethin does too."
Jenkins added that she still struggles to deal with life in the spotlight.
"I love what I do but all of this fame wasn't something I anticipated," she said. "There are parts of it I find a lot harder to deal with."
