Lily Allen is all "Smiles" during a food run at In-N-Out in Redondo Beach, California. The U.K. star stocked up on fountain drinks during her pit stop -- perhaps the singer wants to make the most of her time on the west coast, where the entire chain of popular burger joints is located!

Allen isn't the only fan of In-N-Out -- Miley Cyrus was recently snapped in the drive-thru of the restaurant!
