Her MAC Viva Glam lipstick just dropped in the US, so how did Miley Cyrus celebrate? With a pizza bigger than her, of course.

[related] The charitable, cheese-loving popstar hosted an event to celebrate her new lipstick and lipglass, and uploaded some cute snaps to Instagram.

Posing with the huge pizza, delivered from Big Mama’s & Papa’s Pizzeria in Los Angeles, Miley wrote, “Howddddd deyyyy knowwwww #bigmama #vivaglam.” Clearly someone was pleased with the snack selection!

Rocking a gingham crop top, mini skirt and jacket, we don’t know where on Earth Miley puts all those carbs. However, we salute her, and hope she keeps enjoying Big Mama’s pizza for the foreseeable.
