Rumors about marital discord between Katy Perry and Russell Brand continue to grow, after both were spotted recently without their wedding rings.

The couple recently spent the Christmas holiday apart, fueling rumors that their marriage was on the rocks. A solo Perry was photographed before Christmas splashing in the surf around Hawaii, which could explain the absence of her wedding ring.

But then People reported that her husband Brand, who spent Christmas miles away in the UK, stepped out on a London street Thursday, also without his wedding band.

Reps for Perry and Brand did not respond immediately to ABCNews.com's requests for comment. And their normally active Twitter pages have been unusually mum on the issue.

Us Weekly reported that Perry and Brand had "a massive fight" just before Christmas and instead of flying her family via private jet to Brand's London hometown for the holidays, the singer changed course and flew to Hawaii with friends.

Perry, 27, and Brand, 36, wed Oct. 2010 in India after a whirlwind romance. Earlier this month, Brand brushed off reports of problems, telling Ellen DeGeneres, "I am really happily married."
