Lauren Conrad LCONRAD092707_02.JPGSo, L.C. was at Us Weekly's Hot Hollywood party last night at Opera, and so was Heidi... blah blah blah. More importantly! How do you think Lauren handled the news of ex b/f Jason's engagement on The Hills this week?!

(Below is the vid of the party - look out for Audrina and Justin Bobby in the middle. Why hasn't she ditched him yet? So much drama!)
