Well that's too bad. Peter, also known as Carlisle Cullen in Twilight, and Jennie, from the original legit 90210 series, had been married for 11 years and have 3 daughters. I am not sure if they are important enough for the real reason for the split to get dug up. Usually you see the B-listers sticking together unless one of them jumps up to the A-list...which is often when splits happen.
I don't think this split is career related. Too bad for their kids.

XOXO
