Oh he's been doing it long before Paris and Nichole. They probably stole it from him! LOL!! My husband and I do it all the time, too. When we are getting ready to go out someplace I will ask my husband if I look just okay or haaaaaaaaaaaaaaaaaaahhht.
LOL, Wayback-machine Kitten! We do the VERY same. My husband knows to ALWAYS say I look haaaaaaaaaaahhhhhhhhhhhhhht. (He really thinks so though, so that's cute.)
Here in Chicago, our guy friends say it more like the "a" in "hat," but I as a woman, say it more *bored*, and with an "o" as in "hot."
I won't deny that I like being told that I'm haaaaaaaaauuuuuuut. How can you help but smile at that? :-)
