Alicia Keys Pregnant Rumors, Flaunts Baby Bump in Met Gala Dress? [PHOTOS]: 'Girl on Fire' Songstress Parties Sans-Alcohol, Expecting Second Child with Hubby Swizz Beatz?

Back in February, rumors hit the web that "Girl on Fire" songstress Alicia Keys was pregnant with her second child from hubby Swizz Beatz. The pregnancy buzz soon died down when the Hollywood power couple failed to comment on such exciting "baby news." But now, MediaTakeOut exclusively reports that 32-year-old Keys is "indeed" expecting... just check out the tiny baby bump she was flaunting in a sexy gown at the prestigious Met Gala earlier this week! Do fans really believe this is physical "proof" that Keys is preggo? An inside source for the popular gossip webloid reveals that Keys also attended a huge celebrity after-bash following the stylish event... and she partied without taking one sip of alcohol. Is baby Egypt Daoud Dean soon-to-be a big brother?

Earlier this year, a celeb blogger who goes by Sanda Rose announced that Keys and Beatz were officially expecting their second child together... and the couple was "ecstatic." An alleged source said they were hoping for a little girl, explaining, "She loves Egypt to death and she wants to give him a little sister to play with... [Keys] tired of being the only woman in the household."

(FYI: Keys married Kasseem 'Swizz Beatz' Dean in July 2010 - they welcomed baby boy Egypt in October that same year).

Now, MediaTakeOut insists that Keys is even beginning to sport a mini-baby bump. The proof? Keys' Jason Wu halter dress the singer rocked on the Met Gala Red Carpet in NYC Monday evening (May 6):

Hmm... do fans think Keys is trying to hide something under that sparkly leather ensemble? (The same baby bump rumors are also currently surrounding fellow songstess, Beyonce).

Apparently a snich for MTO confirmed that Keys partied sans-alcohol following the Met Gala event. When this "source" questioned Keys about it (asking if she was pregnant), the Grammy Award winner just slyly smiled, but refused to answer...

Is a big congratulation in order? Stay tuned for more baby bump gossip...

Here's a personal "Message from Alicia" video posted back in June... where the singer talks about how happy she is with her life right now:
