Yes, BJ had one daughter, and so did Leslie (Alyssa). I think Alyssa is with her dad's side of the family. I doubt Jane has gotten better, unless she went to rehab and is being treated for her mental illness. Even if she did, history is not on her side. Her lawyer probably made her delete her social media to look better for the judge, which was a smart move, considering her crazy was on a full display on Facebook.
Here is the Reddit thread I was referring to:
https://www.reddit.com/r/NickCarter/comments/1k9cw31/bella_carter_bjs_daughter_is_with_jane/ It has a link to a GoFundMe that Bella's father's family started to raise money for their legal fight. The last update from April tells the whole story.

I'm sure they knew a lot of people who don't usually watch this stuff would tune in just for that and turn it off right after the performance. It was a great finale to the show though! I'm also glad they made it a whole medley. I'm not sure if they looked tired so much as old LOL. They all look great, don't get me wrong, but those age lines around their eyes are starting to show. I think they've started rehearsing for the Sphere shows, though, so between that and the flying back and forth some of them had to do, I'm sure they probably were tired too.
