Liv Tyler's Knight In Shining Armor

Liv Tyler, 31, and her son Milo William Langdon, 4, were seen out and about in Hollywood on Tuesday. Milo was dressed as his mother's knight in shining armor.

The adorable 4-year-old not only dresses like a little charmer, he talks like one too: “He likes to call me his princess. He says, ‘Oh, mommy, you’re so cute. You’re my precious, precious mommy.’ He’s at that age now where he’s so sweet and so loving and says the sweetest things to me.”
