Katy Perry and Russell Brand most tweeted ex-couple

Washington -  Katy Perry and Russell Brand’s split managed to attract the most attention on Twitter, according to a recent analysis.

In the first 30 days after the pop star and British comedian announced their divorce, in late December, more than 2 million tweets emerged mentioning the estranged couple, according to an  analysis of tweets on five recent celebrity breakups provided to ABC News by the Twitter tracking company Topsy Labs and the Web newspaper The Daily Dot.

The reality star Kim Kardashian and her basketball player ex-beau Kris Humphries, came in close second as their October split generated more than 1.4 million tweets.

Surprisingly, tweets mentioning Kutcher and Moore (who still uses the Twitter handle “mrskutcher”) for the first 30 days after their breakup totaled just fewer than 300,000 — despite the fact  that Kutcher was the first person to amass 1 million Twitter followers.

Owen Thomas, the founding editor of The Daily Dot, said the Twitter breakup reaction stats seemed to reflect celebrities’ overall fame.

“It’s not how hip they are or how active they are on Twitter, it’s how many people know them, period,” he said.
