Salma Hayek went clothes shopping for a baby girl! Ay dios mio!

TMZ has learned that very pregnant Salma, dressed in a slate blue jersey dress and black ballet flats, hit West Hollywood's trendy Bel Bambini baby boutique on Tuesday and bought $1,500 worth of pink items for a newborn. La niña!

For added privacy (or to make room), the store closed for almost an hour as sexy Salma shopped with her mom. A fellow shopper, who happened to be in the store before it closed, told TMZ Salma was overheard saying in Spanish, "This will be perfect for her," -- about a pacifier. Fantastico!

Once she was done with her compras, Salma was ushered out the back where her driver was waiting. Take big mama home! If gorgeous Salma is having a girl -- one thing's for sure -- she won't be an ugly Betty!
