In the past month, Elin Nordegren has spent the night over at Tiger Woods' house a handful of times as they attempt what The Enquirer is calling a trial marriage. Or, Tiger could have just been lazy and didn't want to log on to the computer and search through escort ads or listen to Lindsey Vonn complain about how much her knee hurts and how they should wait a few more days. Yeah, how does the Elin sleeping over work with the whole Lindsey Vonn dynamic. Is this a one night on one night off thing? Does Tiger have an understanding with Elin? Something like he gets to sleep with Lindsey and Elin promises not to hit him with a golf club? The couple were spotted together (above) over the weekend for the first time in years.
