Paula Patton -- Robin Lays it On Thicke With Floral Assault

Robin Thicke is GUILTY of a floral assault ... bombarding his estranged wife with begging-for-forgiveness bouquets ... at least that's the way it seems.

Paula Patton's Hollywood Hills home was inundated with gigantic, expensive floral arrangements Thursday ... hours before Robin got on stage and told the audience he's gunning to get his girl back.

True enough ... it's possible Robin didn't send the flowers, but it would be remarkably coincidental that they came from someone else.
