Lil Wayne Disses Christina Milian, 'Baby Mama' Flaunts TNT Love? [PHOTOS]: Rapper's Daughter Reginae Carter Still '#1' Lady Amid Pregnancy Rumors

Things continue heating-up between rumored couple Lil Wayne and Christina Milian - but is Weezy not taking this blossoming "relationship" as serious as the "Believer" songstress?

Earlier this week, Milian shared this cute snapshot on Instagram:

christinamilian: "I love you Robyn! Thank you for my necklace! This makes me VERY happy. You're so sweet and always thoughtful! #TNT  love #TTU."

As several fans already know, TNT allegedly stands for "Tina and Tunechi" - the couple's "secret" nickname.

Not too long ago, Milian actually got the acronym shaved into the back of her head - now that's dedication!

She's obviously falling pretty hard for the YMCMB rapper. Rumors even suggest that she might be expecting the New Orleans emcee's baby...

But still, Weezy doesn't consider "Tina Turnup" the leading lady in his life right now...

liltunechi_c5: "Aint no woman alive that culd take my daughter place!"

How cute! That's Wayne's teenage daughter, Reginae Carter - daddy's little girl!

Is this the "How To Love" superstar's attempt at throwing sly shade at Milian? Perhaps things are moving too fast for his taste...

Do Mstars readers believe there's any truth to the pregnancy rumors?

Interestingly enough, apparently Weezy's still engaged to longtime girlfriend, Dhea Sodano. Supposedly, he bought her a flashy $250,000 diamond ring instead of a chain necklace to honor their love...
