Miami might be known as a party town, but last night it was transformed into “the city of love.” At Club Mansion, Kim Kardashian hosted a NYE bash with her sisters and was joined by her beau Reggie Bush.

When the clock struck midnight, Kim planted a kiss on Reggie. The two have been very cautious of their relationship in the past, but it’s obvious now that it’s getting pretty serious.

A couple blocks from Mansion, Ashlee Simpson and Pete Wentz hosted a NYE bash at the Shore Club hotel. The two rang in the New Year with a long kiss. With so much smooching we want to know what 2008 will bring for these couples, maybe engagements?
