Nicki Minaj vs. Christina Milian: 'Anaconda' Beauty Shares Cute Lil Wayne Birthday Instagram PHOTOS Amid Baby Bump RUMORS

Rumors are currently swirling online that Christina Milian is pregnant with Lil Wayne's baby. Apparently, Weezy's relationship with the "When You Look At Me" songstress continues getting more serious - and they could be expecting a baby together!

Is Wayne's YMCMB sweetheart Nicki Minaj jealous?

The "Anaconda" rapper recently posted a slew of Instagram photos featuring the "How To Love" emcee in honor of his 31st birthday:

nickiminaj: "Love u so much. #HappyBirthdayLilWayne #YMCMB."

nickiminaj: "#HappyBirthdayLilWayne."

nickiminaj: "My babyyyyyyyyyyyyyy... 7 years later. It's still just #US #HappyBirthdayLilWayne #Legend my #everything #YoungMulaBabay!!!!"

Rumors once suggested that the two frequent collaborators were romantically involved. But for now they remain "close friends" and associates.

Milian threw a "surprise" b-day bash earlier this week (the New Orleans native was born on Sept. 27). Perhaps Minaj wasn't invited?

The popular gossip webloid MediaTakeOut.com insists that Milian's definitely flaunting the beginning signs of a baby bump. She was also allegedly spotted at the OB-GYN office recently. Do readers believe the pregnancy rumors? 

And is a new "beef" brewing in Hollywood between The Pink Print songstress and Weezy's new main squeeze?
