My Best Friends Wedding?

Julia Roberts character has just let her best friend michael marry Kimmy, she is sitting at a table alone, depressed and Rupert's character calls and says she did the right thing and describes what she is wearing and that she has not eaten her cake.. then she realizes she never told him what color her dress was figures it out that he is acutally there at the wedding..

he calls tells her she's sitting there in her violet dress strumming her fingernails on the table wishing she had stopped in all her plotting to get that manacure she so desperately neeeds hasn't touched her cake. Then a familar song begins to play and she looks around and the crowds part and she see a handsome man standing there on the phone as is she and she knows he is *whisper* gay and then they dance to the moment I wake up or whatever the name of the song is

I think he just describes what she's wearing, what she is doing and then goes into giving a play-by-play describing their every move. Can't remember the words - sorry!
