The American singer turns 42 today, and Carey proves that there's no going downhill when it comes to birthdays, because she's still struttin' her stuff and overcoming any obstacles that may come her way.In the past year, we've seen Mariah give birth to adorable twins Monroe and Morocco, launch a website for "dem babies," stay by her hubby Nick Cannon's hospital bed and even share a bare-faced photo of herself in the studio.
Happy birthday, Mariah!
