Taylor and Laura also married, four years later. They haven't been able to have any kids (probably partly thanks to that bullet) but they have adopted twins.
Zac and Bree are dating. Of course, it may be noted that when they announced that they were, then general response was "it's about time". Zac is now trying to get the nerve to finally propose.
Hanson is still going strong, they even have their own record company now entitled 'MOE Records'. Two thirds of their signed artists have had at least one single at number 1. (Of course what we're not mentioning is that they currently only have 6 artists).
Diana and Walker have had two more children since then (Isaac was right), Karen and Trey. Mackie and Zoe have started their own band, signed by MOE Records of course, (and naturally they're one of the ones with number 1s), which Karen may be joining, and maybe later Trey as well (after all, they're only 7 and 4 at the moment).
THE END
