We haven't seen them together since Paris got sprung from the Lynwood lock-up, but last night the Simple Lifers reunited at the Chateau over dinner with Nicole's alleged inseminator, Joel Madden! Although she was there for dinner with her friends, we caught Paris (looking demure in a DVF dress) flirting with a new guy!

But Paris sped away from the Chateau alone (her driver practically ran over a photog in the process), while Joel hid his girlfriend in the back of her car! Is Nicole beginning to really show?
