Is that the beginning of a baby bump we see?!

On Monday Pink departed from Los Angeles International Airport in a loose maxi dress, and she totally looks preggers to us!

The 35-year-old singer and husband Carey Hart welcomed their first daughter Willow four years ago, and they recently listed their mansion in Malibu for $14 million. Is it possible that the two are on the market for a new family home after learning that she's expecting their second child?

She probably wouldn't tell our photogs, but we're thinking an announcement might be coming soon...
