Underage Thinking had Kristin sinking.

Despite her reputation as Laguna Beach’s most wanted, it sounds like she needed to muster every ounce of confidence she had to catch the attention of singer Teddy Geiger. The New York Daily News claims that Kristin Cavallari, currently single again after her second split from D-list celebrity Brody Jenner, was spied obsessively text-messaging the 17-year-old singer after she co-starred with him in his For You I Will (Confidence) video earlier this year. Kristin, who is rumored to have also been involved with Matt Leinhart and Nick Lachey (albeit not at the same time), was apparently uncharacteristically unsuccessful in getting Teddy’s time of day back then, possibly as a result of the warnings of his handlers, clearly familiar with Kristin’s history of "open relationships." Guess not everyone wants to be her Love Monkey.
