Christina Aguilera may be in the middle of a worldwide Back to Basics tour, but she says husband Jordan Bratman knows how to keep the romance alive despite the distance.

“He’ll fill my room with balloons and I won’t be expecting it,” she told PEOPLE Wednesday at a party in New York City for her Nylon magazine cover. “I’ll come in the room and there will be balloons everywhere and a card and my favorite chocolates all around – and I’m always sending cards when I can, just cute little love notes.”

It doesn’t stop there. “He always leaves Post-Its by my bed when I wake up in the morning telling me how much he loves me. All that gushy stuff, but it feels good. He’s the best,” Aguilera, 26, said of Bratman, 29, whom she wed in 2005 and calls her “best friend in the whole wide world.”

What else makes their marriage work? “Naked Sundays definitely keep it spicy! And we make sure that we always have fun together and keep it fun and sexy. We went to Disneyland with a couple of friends on Valentine’s Day, keeping it super fun and light. We go out to romantic dinners a lot. We always make key spots, dim, sexy spots. We do anything your average couple would do, but with an interesting twist.”

And while Aguilera says that she and Bratman “do plan on having a family,” don’t expect to hear pregnancy reports any time soon. “I do have a schedule for myself and goals I want to achieve, but it’s definitely on the list of things to do in the next few years,” she said. “We’ll have fun trying in the meantime!”
