pls call me "Leng Lui"

One of my girl friends is getting married. So she asked me how i want her to address me in the wedding invitation card: "Ms. XXX and partner" or "Mr & Mrs. xxx". I was trying to be cheeky and replied "Ms. Leng Lui" should be good enough. She said okay and she will put this "XXX's si lai". @#$@#$@

leng lui - pretty girl
si lai - old haggard housewife

I think i still prefer "Mr & Mrs. xxx" :P :P :P
