The guy who's famously had multiple girlfriends at once just got a BIG ASS BED ... and we think we know why.
L.A. Clippers star Lou Williams showed off the new centerpiece of his master bedroom on Wednesday ... and the thing is big enough to fit like, 4 Shaquille O'Neals.
Williams captioned his IG pic with "California wasn’t big enough" ... and he wasn't lyin' -- the folks at MAREE tell us he got a bed 4 feet wider and 3 feet longer than a regular California King sized bed.
Now remember .
