Ha! I never thought I’d have the opportunity to say “XYZ” in that context ever again, much less to Dave Navarro.

Davey left Teddy’s last night with a mystery blonde and an open fly — can anyone ID this chick?

Everyone seemed to be in a genuinely good mood on Sunday at the Disney-sponsored event to support the Elizabeth Glaser Pediatric AIDS Foundation in Westwood.

Jamie-Lynn Spears was there with an unidentified guest (a boyfriend, maybe? Anyone know who this Abercrombied hottie is?), and, boy, she must just be really happy that it’s not her sister in jail right now. A very pregnant Bridget Moynahan was goofing around with an adorable Molly Sims. Lauren Conrad showed up with Audrina Patridge (not surprisingly, there was no Heidi Montag in sight). Carmen Electra showed up, as did ex-hubby Dave Navarro (wearing the most adorable little shirt — I’m pretty sure I got the same one at Banana Republic a few seasons ago). Brooke Burke even brought a cowboy hat. And, of course, my darling Ashley Tisdale, once again investing her time and energy in charity rather than partying.
