So we saw Fergie do "Glamorous", "Big Girls Don't Cry" and "Fergalicous" outdoors in a traffic circle in 100° heat. She seemed like she wasn't hating the whole experience, which is pretty good given the heat and that there weren't really many people there. You can see pictures of the event here (chose "7-21 Denver VZW In-Store"), and I may post pictures later if I have any good ones...
Then we stayed and had coffee drinks at Borders, then went to Denver's Kwik-E-Mart and on to the Blue Bonnet Cafe for dinner (a Denver institution we had never been to before).
BTW, did you know Fergie was in Wild Orchid? I didn't until just now...
