ROBIN THICKE and PAULA PATTON have split after over eight years of marriage . . . one pregnancy . . . and a terrible performance at the "VMAs".


They released this statement:  Quote, "We will always love each other and be best friends, however, we have mutually decided to separate at this time."  They have a three-year-old son named Julian.


It's unclear what happened, but there have been rumors about the end of their marriage since Robin's performance with MILEY CYRUS at the "VMAs", and the photo after the show when he was caught grabbing a woman's BUTT.


Interestingly enough, that woman is weighing in on the split.  She says, quote, "Robin acting like that with me makes me think there were many more.  It's a shame because when you have a kid, it's upsetting."


Still, it sounds like she'd be up for more of Robin's butt-grabbings.  She says, quote, "I'd love to grab a drink with him if he asked."
