Selena Gomez steps out to buy cigarettes after Justin Bieber arrest

Selena Gomez is not worried about her ex-boyfriend of two years getting arrested for DUI.

The "Come & Get It" singer was spotted out and about in Los Angeles Thursday just hours after her Canadian ex-boyfriend was arrested, booked and released from jail in Miami.

The 21-year-old Spring Breakers star was all smiles as she payed a visit to a local gas station where she purchased a pack of cigarettes and a large cup of soda. Gomez wore tight black pants and a beige, cleavage-baring top under an oversized sweater during her outing. She accessorized the look with one of her controversial bindis and dark sunglasses.

Early Thursday morning, Gomez's on-again off-again beau was arrested in Miami Beach and charged with driving under the influence, drag racing, driving with a suspended license and resisting arrest without violence. At the time of the arrest, the singer told authorities he had consumed beer, anti-depressants and had been smoking marihuana all day. He was released on a $2,500 bail.

Gomez and Bieber were last seen together in early January as the two rode Segway scooters around Bieber's Calabasas, Calif. neighborhood.
