Who is the Asian girl who goes to . . . .

. . . . the party (that occurs about 15-20 minutes from the end of the movie) with Pete McCoy (actor Gardner McKay), the young newspaperman who is at odds with Brian Keith?

No Asian actresses appear in the imdb credits, but this woman sure looks an awful lot like Irene Tsu, who was very busy in this era of Hollywood films.

Any ideas?
