if you can wait till tomorrow, i'll be happy to talk explicitly!!! until then, crack_van is great, pop_reference answers specific requests, and maybe this (http://www.livejournal.com/users/just_temporary/803.html) will give you a couple of more links.

as for 1: justin timberlake and nick carter are in their early 20s (22 and 23 I think) and lance bass is like a year older (too lazy to look up birth years).

Happy Mother's Day!!!
