The actress was thought to have rekindled her romance with her Twilight co-star after apologising for cheating on him with married director Rupert Sanders, but during an interview on US TV to promote the final film in the vampire saga, Kristen remained tight-lipped and said she would leave people "guessing".
Kristen was asked about the status of their relationship on The Today Show, and replied: "Funny you mention that."
The 22-year-old went on: "I'm going to just let people watch whatever little movie they think our lives are...
"Keep 'em guessing, I always say."
Kristen has previously indicated that she and R-Patz have got through their rocky patch, telling reporters at the Toronto Film Festival a few weeks after her affair emerged: "We're going to be fine. We're totally fine."
The couple have also been spotted out in recent weeks and are now promoting the final Twilight film, Breaking Dawn - Part 2, together. This week they were snapped boarding a private jet in Los Angeles, sporting matching outfits of jeans, white t-shirts and backwards baseball caps.
The movie arrives in cinemas later this month.
