Bachelor couple Sean Lowe and Catherine Giudici have another reason to celebrate in the new year – Jan. 26 marks their first wedding anniversary!

So what have the two been up to since saying ”I do” in front of 6 million television viewers and honeymooning in Tahiti?

“There’s been a lot of down time with just us two,” Giudici, 28, tells PEOPLE exclusively. “I’ve really been enjoying being next to him all the time.”

Lowe, 31, add that he still feels the same spark for the Seattle native as when they met on season 17 of the show in 2013.

“What originally attracted me to her was her outgoing, goofy personality,” Lowe says. “We’ve kept that alive and it just kind of keeps our marriage fresh and young.”

The bottom line?

“Keep it fun,” Lowe says.

Lowe, who got his start on Emily Maynard’s season of The Bachelorette, says he has big plans for their anniversary celebration – but it’s top-secret.

“I’ve got a surprise planned for her, so I’ve got to keep it under tight wraps,” Lowe reveals. “But we’ll celebrate it in a really good way.”

Now that the pair has made it to the one-year mark, those inevitable Bachelor baby murmurs are growing louder, but Giudici says she and Lowe are in no rush.

“We are just enjoying each other right now,” Giudici says. “But yeah, the future obviously holds a big family.”
