The wig prank continues

Caroline Wozniacki is the latest player to pull a wig prank on Facebook. However, unlike Victoria Azarenka who copied Maria Sharapova, Wozniacki is a bit more original by putting on a black one.

Still on Wozniacki, she'll be on the February issue of Expatriate Lifestyle (Malaysia version). There will be an exclusive interview inside. I haven't purchase the magazine yet but I will share the content once I get hold of it.

Mom-to-be Kim Kardashian hangs out with Serena Williams

Kim Kardashian enjoyed a night out with girl pal Serena Williams without boyfriend Kanye West. They had a dinner at Nobu restaurant in Los Angeles.

"I simply cannot get out of bed," Williams tweeted earlier that evening, to which Kardashian replied, "You better! We have dinner tonight!"

Despite her exhaustion after long weeks at the Australian Open, Williams ended up having a great time with Kardashian.

They even took a picture together and Kardashian tweeted "Fun girls night!!! But where's my nose @serenawilliams ??? Lol #tooflashy."

"Such a fun night," Williams agreed. "Love you!"

Infographic: Who are the social media champions of Australian Open 2013?

The guys at IBM has analysed social media posts across Twitter, Facebook, news sites, blogs and videos to understand fan sentiment for the first time at the Australian Open this year.

Some of the predictable facts are Maria Sharapova's first tweet (she has garnered more than 115k followers so far), Sloane Stephens tripled her Twitter followers since defeating Serena Williams and Bernard Tomic being the most popular Australian player at the Grand Slam.

There are a couple of surprises though. Firstly, Victoria Azarenka's negative sentiment is way lower than I expected and secondly, Li Na is not even listed among the Top 5 popular female players ranked by number of positive mentions. It doesn't make sense to me.

So, what do you think?
