There has been rumors that she was pregnant which she ended up
confirming showing herself with a big belly at Diddy's all white party and twitting about it.
He was interviewed by Radio Big Boy where he asked him, if there was any rumors he wanted to squash, like Lauren London and commented that she was fine and Lil Wayne agreed and then he went ask if she was very pregnant with his baby, and he just said "very pregnant, yes". and He went on by saying So i take that as a yes, she's very pregnant and Lil Wayne ended by saying this : “That’s not rumors. That’s a kid, that’s a child, that’s a life. You don’t hide from that!,” responded the rapper. This doesn't surprised me because Lauren has previously mention that she loved bad boys and others has been saying He was her first. If i remember right few website claimed Lil Wayne had a tattoo with Miss London's name on his right arm. I can't assure you that it is indeed true it could have been photoshopped. If this is his child this will be baby number 3 and if Nivea is pregnant for him which i would believe as well it would end up being Baby number 4.

I won't take that as a yes or no i take that as a hey believe what you want, I'm lil wayne I don't need to justify my life. There you take it the way you want.
