Hilary Duff Luca Christmas Jamer Perse photo bomb

Yesterday Hilary Duff and her adorable son Luca went shopping at James Perse in West Hollywood, and Hil's little boy wore a Santa hat and appeared to be quite the trooper while his mom indulged in some retail therapy.

Later in the day Hil and her boy made gingerbread houses, and she posted the pic below on Twitter and wrote, "My new ride..." It appears as though Luca made her a gingerbread truck ... is that not the cutest thing ever?!
