WE GOT THE FIRST PICS OF NICKI MINAJ SINCE BEING BEATEN . . . AND HER LIP LOOKS SWOLLEN!!!

. Since being VICIOUSLY ATTACKED by her now EX boyfriend Safaree Samuels, Nicki Minaj's security has worked EXTRA HARD to stop anyone from getting a photo of her.

Luckily we managed to get our hands on two pics - taken DURING HER HOUSTON CONCERT on WEdnesday. These photos were taken about 24 hours AFTER Safaree SMASHED her in the facewith a suitcase.

The pictures show Nicki has some SWELLING on the RIGHT side of mouth under her lip.
