Jessica Simpson was very mindful of her tan lines as she and mom Tina had some poolside QT yesterday in Cabo San Lucas. With all the conflicting reports about Jess and Tony's behavior at Ashlee's wedding on Saturday, it's hard to tell what exactly went down with those two — but based on the first wedding photos, it seems like they had a blast dancing. Either way, Jessica seems to be having a great time with her parents, and we're all for anything that keeps that goofy grin on her face.
