Let's take a look at the timeline.
Friday*: Jake is seen publicly for the first time since the announcement. Clearly still in shock, he walks around wearing half of an all-black mourning ensemble.
Saturday: Distracted by his grief, Jake commits the costume tragedy captured in the previous post. No doubt his mask is to hide his tears.
Sunday: Having not changed pants in three days, Jake drowns his sorrows in an all-night bender with Danny Bonaduce.
Monday: As Jake takes a day to mourn privately, the following is reported by Variety, "...'Nailed,' directed by David O. Russell and starring Jake Gyllenhaal and Jessica Biel..."
"Nailed." With Jessica Biel. What stage of grief is that?

And we'll see what tomorrow brings. Never a dull moment...
Thanks to heddaparsons for the Biel bit.
* Note that the dates are roughly as accurate as my description of the pictures and my identification of Danny Bonaduce.
