Squeaky-clean Selena Gomez pictured buying cigarettes morning after ex Justin Bieber's DUI arrest

They're the first pictures of Selena Gomez to emerge in the wake of ex-boyfriend Justin Bieber's arrest in Miami for DUI in the early hours of Thursday morning.

And in an uncharacteristic move for the squeaky-clean star, she shocked fans as she stopped to pick up a packet of Djarum cigarettes shortly after leaving home in Tarzana, California.

The actress gave little away as she shielded her eyes behind large black Ray-Ban sunglasses, though she appeared to be putting on a brave face as she plastered on a decidedly awkward grin while her love sat in jail on the other side of the country.

The 21-year-old, who was thought to have recently rekindled her on-again, off-again relationship with the 19-year-old singer, gave her ex a good look at what he's missing in her obviously well-thought-out ensemble.

The star showed off her toned figure in a nude-coloured halterneck body suit with plunging neckline, which she teamed with black skinny jeans with gold zipper pocket detail.

She completed her glam wardrobe with black Louboutin booties and a long flowy black cape-style cardigan.

A long gold tasselled necklace featuring an emerald pendant was draped several times around her neck while she also wore a rose gold bindi on her forehead.

The stunning brunette wore her hair loose in messy waves and kept her make-up minimal and natural, with a soft pink hue on her lips.

While the pair have recently been caught up in a series of controversies - including allegations of rude and vile text message exchanges, which were denied by Selena's rep - they have recently been seen together on several occasions as they reportedly get their relationship back on track.
