We miss the good ol' days.

In the latest episode, Jack heeded the advice of a 15-year-old  daughter, Kate, stepping behind the wheel -- after having a few beers -- and making the two-hour trek to Cleveland, Ohio, where Rebecca’s first concert of a five-city tour (which happened to include an ex-beau) was kicking off, all in a last-ditch effort to fix his marriage.

Who knows what lies ahead for the couple in the immediate future, but one thing’s for sure: The honeymoon period is over.

Because we here at ET are all about Jack and Rebecca’s happier days, we’ve compiled the best of their most romantic and sweetest moments from the first season.
