The funding deal could be announced as early as this week, and will be led by Silicon Valley VC firm Andreessen Horowitz, according to sources cited by the Wall Street Journal. According to the report, Foursquare has also been in serious acquisition talks with Facebook and Yahoo.

Last September Foursquare received a $1.35 million injection from New York City-based Union Square Ventures, according to an SEC filing. The service, which lets users share their current location with their friends via their mobile devices, reported 1.7 million users last month in a Twitter post.
