"The girls held hands and were with each other the whole time. Every time I see Lindsay, there's Courtenay. They are always together."
While at the party, Lindsay, 21, and Courtenay, 28, referred to themselves as "roommates" and told guests they had been living together in Los Angeles for about a month. They left the party together and were seen shopping in Beverly Hills the next day.
A representative for Lindsay: "The two are good friends, nothing more."
