Ricki Lake says she’s always felt sexy around her fiancé Christian Evans.

“Oh, my god, my love is pretty spicy,” the TV personality, 43, recently told PEOPLE.

With a long chuckle, Lake says that she now incorporates her hard work for Dancing with the Stars into her private life.

“When I get home [from rehearsals], I train horizontally,” she said. “[My fiancé] has noticed a difference in my stamina over the last couple of weeks.”

But a bashful Derek Hough, 26 – who stood by his partner’s side as she dished about her deets between the sheets – tried to cut the conversation short.

“Derek knows all about [my sex life],” Lake admitted unashamedly, as Hough turned his head. “He hears about it. Derek and I have gotten to know each other, so, you know, I share stuff with him.”

Hough, who stayed mostly mum on the taboo topic, would only say, “I guess that means I’m not working her hard enough during rehearsals. I want her to go home and collapse.”
