No word yet on the color of the bundle, but Pink's a mommy-to-be!

A source tells the new Us Weekly (on newsstands Wednesday) that the singer, 31, and husband Carey Hart, 35, are expecting their first child.

"She's 12 weeks along," says the insider. "She wanted to do it between tours, when she has some time off."

The source adds that after the duo’s 2008 separation, “Pink was determined to make the relationship solid. Now she’s really happy, and she’s excited she got pregnant so fast! She’ll be a brilliant mother.”
