And They Call It Puppy Love

Singer Jesse McCartney arrived at Los Angeles International Airport on Saturday and was welcomed with a big juicy kiss from girlfriend Katie Cassidy, daughter of "Partridge Family" teen idol David Cassidy.

Katie is one of the few surviving cast members of the upcoming "Dallas" movie (everyone but Katie and John Travolta left the project).

The puppy love couple was caught kissing near baggage claim. Katie rushed her loverboy as soon as he was in sight!
