Who

KATY PERRY & RUSSELL BRAND

From denial to split: 1 month

What a difference a month makes! On Nov. 31, 2011, the singer playfully denied that she and her comedian husband of a year were calling it quits. "First I'm pregnant & then I'm divorced. What am I All My Children?!" she joked on Twitter. Only four weeks later, the two had stopped wearing their wedding rings and remained awkwardly silent about their marriage as they spent the holidays separately. By Dec. 30, 2011? Yep, you guessed it: Brand filed for divorce.
