Kelly Brook recently revealed she was three months pregnant with boyfriend Thom Evans after meeting him last November.
Clearly over the moon about starting a family together, the couple talk exclusively to HELLO! magazine about their love story and the baby girl they're expecting.
Relaxing at Thom's parents' villa in the Algarve, the model and actress, 31, says of the surprise pregnancy: "This is what happens when you are in love.
"You surrender to whatever is to be. It wasn't a plan, but if it happened, it happened.
"We were boyfriend and girlfriend."
Thom – a 26-year-old former Scottish rugby union international – adds: "It helped that I was head-over-heels in love with Kelly.
Remembering the moment Kelly shared the exciting news, he said: "When she told me on Christmas Eve, it didn't even feel like a complete surprise. I had a feeling she might be."
To which Kelly quipped: "I got some diamond earrings and he got a baby!"
On a more serious note, Kelly reveals she knew instantly Thom was her Mr Right.
"I love Thom and Thom loves me. We love being together. It is as simple as that," she said.
"I immediately felt he was The One, and I have never felt that before."
