Janet Jackson's estranged husband looks like he has a go-to spot to hang with their baby boy, and he knows just where to park it.
Wissam Al Mana was holding baby Eissa Monday in London on a park bench -- one he appears to frequent with his kid.
As we reported ... Janet and Wissam split back in April and are in the throes of a divorce. Their son was born just a few months before the separation.
You'd never know from looking at the pic ... Wissam's a billionaire.
