According to reports from Reuters Mark Zuckerberg, CEO of Facebook, is in talks with Skype about the possibility of either buying the company outright or forming a joint venture.

Reuters revealed the news based on information from two 'reliable sources', with one saying Facebook is weighing up the benefits of buying out Skype for between $3 billion and $4billion.

With Skype having recently appointed a new CEO they have delayed their initial public offering (IPO) until later this year, but initial reports suggest it will only be around $1 billion.

The second source claimed there won't be a buyout but rather a joint venture between Facebook and Skype, which given the working relationship the two already have seems to be a more viable option.

When Skype released its version 5.0 software for Windows, it included a Facebook tab that let users chat or call Facebook friends via Skype, right from the Facebook newsfeed that can be viewed from within the Skype application.

If Facebook are to act on either option they will have to beat off competition from Google, who, according to one of the sources, are also in 'early talks' with Skype.
