This is a bit complicated, so hold on tight: Britney Spears' first husband, Jason Alexander, is dating her ex-husband Kevin Federline's ex-girlfiend, Shar Jackson. Confused?
Britney and Jason were married for 24 hours in Vegas.
Kevin and Britney were married once upon a time, and have two kids.
Kevin and Shar also have two kids between them from a previous relationship.
According to a report by Radar, a source close to Shar and Jason says that the pair "were introduced several years ago at a gifting suite in Los Angeles and have been friends ever since, but a few weeks ago began dating."
It's a regular daytime soap opera plot line, convoluted enough that we thought it warranted a diagram. Enjoy.
