And the happiest celebrity on Twitter is...
One Direction's Harry Styles is apparently the happiest celebrity on Twitter.
The singer came out top when scientists looked at the emotions expressed in Tweets over the last eight months by 100 people with the most followers.
Researchers from Queen's University in Belfast included singer Adele, footballer Cristiano Ronaldo and actress Emma Watson in their top 10.
While talk show host, Oprah Winfrey just missed the top 10, ranking at number 11.
The research is said to inform online users of how to communicate emotions using written text on the net.
Here are some of Harry's happiest tweets.
Looking forward to sharing the next album with everyone. Hope you like it as much as we do. All the love
