Jeanie Buss immediately followed the announcement with a tweet of her own:

From the sound of the comments made publicly available, it appears the end of their engagement was a civil split.

Per ESPN's Baxter Holmes, the two have dated since 1999 and became engaged during the Christmas holiday of 2012 -- an unfortunate turn of events for basketball's most popular duo.
