Christina Milian Baby Bump PHOTOS, Pregnant With Lil Wayne's Fifth Kid? Jas Prince's Ex Throws Rapper Boyfriend Surprise Birthday Party, 'No Drinking Or Smoking'

Rumors suggest that Christina Milian is expecting her second child.... with infamous YMCMB rapper, Lil Wayne.

UPDATE: Christina Milian's OB-GYN Visit Confirms Pregnancy?

Just a few months ago, the "AM to PM" songstress broke things off with (ex) fiance, Jas Prince. She then started a whirlwind romance with Weezy. Some fans don't believe the dating buzz, but Milian just threw the "Lollipop" emcee a surprise party for his 31st birthday, and the two hip-hop stars definitely look "coupled-up" -

Notice that in some pics, Milian keeps "caressing" her tummy. Considering it was her main squeeze's birthday (September 27), she didn't dress too provacative or wild. She kept things rather moderate and casual... maybe in order to "hide" something growing underneath that black tank-top?

According to the infamous gossip webloid MediaTakeOut.com, fellow partiers reveal that the 33-year-old starlet also didn't drink or smoke anything at the event (which is rare).

Will legit baby bump photos surface soon?

Fun fact - Tina Turn-Up actually celebrates her birthday today (September 26).

Meanwhile, rumors suggest that Weezy's still dating longtime fiancee, Dhea Sodano. She might be preggo, too! Do Mstars readers believe all the hype?

If the rumors are true, this will be Weezy's fifth kid. He already has three sons and one daughter - Reginae Carter.

Milian initionally denied that she was "intimately involved" with the New Orleans native - they're only close business partners. Well, these snapshots prove otherwise!

Is the "Baggage Claim" songtress looking a little more "ample?"

Milian already has one daughter with rapper The Dream named Violet Madison Nash.
