Pink Preggers?

Could Pink and on-again hubby Carey Hart be expecting? The pop star was out and about in Hollywood looking like she was going to hit the gym and there definitely could be a bit of a baby bump there. Pink has not confirmed the rumors, but did tweet: “Lord knows when this 600 lb baby comes out I’ve been growing for 8 years.” We hope she’s preggers — imagine the love child of those two?! Adorable!
