Dueling Labor Day Parties

Still in the Hamptons, LuAnn and her kids get a surprise visit from Rosie who is no longer their housekeeper but is still concerned about the family as a whole. The Singers and the Van Kempens meet for dinner and the subject of a comment Mario made to LuAnn comes up. Ramona chastises Mario for the comment so he decides to make a peace offering and leaves LuAnn a voicemail and an invitation. LuAnn isn't so sure about Mario’s voicemail and leans on Jill for advice. Bethenny and Jason head out for a romantic dinner and Jason asks Bethenny to move in with him. It's Labor Day weekend and both Ramona and LuAnn decide to throw parties – the issue becomes which party will the ladies go to? Kelly arrives at LuAnn’s with a secret to share with the other women. Over at Ramona's, Alex and Simon try to make a discreet exit so they can stop by Jill’s, but Ramona will have none of that.
