Lil Wayne's ears must have been burning last night -- 3 of the 4 mothers of his children all showed up in the same place ... and surprisingly ... there was ZERO drama. Nivea, Toya Wright and Sarah Vivan -- each who've mothered one Weezy spawn -- were all at the premiere of "Lucy" in Atlanta. Only Laura London was absent.
It's virtually impossible for two exes to get along ... so to have 3 do so is impressive.
Although Weezy wasn't there -- he could've safely attended. All the ladies are reportedly friends and hold no grudges ... at least outwardly.
Of course, with all of them hanging out together ... who sprung for the babysitters?
You know the answer.
