While promoting her new book I Just Want You to Know, Kate Gosselin denied her ex Jon's claims that she is choosing fame over her kids. (Last week, Jon, 33, filed papers dubbing Kate, 35, an "absentee" mom and asking a Pennsylvania judge for primary custody of their eight children.)

"I am a working mom and cameras are on me, so people catch me traveling or working," she said on the Today show Tuesday (see clip, above). "I've got to work harder now than ever because I am a single mom and in my heart, I am always in my kitchen baking and cooking for my kids, and I will always be there. It is a struggle to be here ... I would rather be at home with them. But I have to work. I have to provide for them. It's a struggle every single mom goes through."

Juggling Dancing With the Stars and motherhood is hard, she said. "I am on the first flight as soon as the show lets me out, and that's my night of sleep," she said. "I get home and I dance and I am done by the time they get home from school and I spend the rest of the week with them. It's difficult." Despite her hectic schedule, she said she makes "the most of every minute I do have with them." Added Kate, "They know I have to work ... they don't like it. But when I am home, we make those little spots of time really big in our memories."
