MILF alert! -- Liv Tyler is one hot mama.

Sporting a short black skirt and matching knee high boots, Liv celebrated her 30th birthday in NYC yesterday with musician hubby, Royston Langdon, and their adorable two-and-a-half-year-old son, Milo.

TMZ spotted the family walking from their pad in the West Village to the nearby restaurant Spotted Pig, the proud parents swinging Milo between them as they hoofed it to the restaurant.
