All of Robin Thicke's on-stage begging and pleading hasn't worked ... because he says he hasn't seen his estranged wife Paula Patton in FOUR MONTHS!!!
Thicke -- who's made very public apologies at the Billboard Music Awards and the BET Awards -- was on "EBRO in the Morning" Tuesday on HOT 97 ... when he said he's been persona non grata with Paula for months now.
But sources connected to the ex-couple tell us that's not entirely true -- he and Paula have literally seen each other several times ... particularly when they hand off their son for visits.
So, maybe Robin's just looking for more sympathy -- but at the same time he admits Paula hasn't even heard most of his new album (which bears her name).
Sounds like it's time for a new approach.
