Google's chief executive declined to answer a question about the company's reported interest in taking over Twitter on Tuesday.

We love Twitter and I like to tweet, Eric Schmidt answered when asked at the Mobile World Congress fair in Barcelona whether he was interested in Twitter.

The reported low-level talks between the two parties valued Twitter at as much as $10 billion, the Wall Street Journal reported last week.

Schmidt added that Google's video-sharing site YouTube doubled its revenues last year, without elaborating. Google does not break out YouTube results.
