t's the biggest night of the year for musicians, so guests at the 58th annual Grammy Awards in Los Angeles on Monday pulled out all the stops when it came to their outfits.

The pop stars showcased their toned stomachs for the occasion, with Taylor sporting a red bandeau top with a hot pink skirt, which was slit open to reveal her matching underwear.

The 26-year-old, who revealed that her outfit was by Atelier Versace, was also showing off a new shorter hairdo, complete with blunt fringe. Meanwhile Selena went for a more glitzy look in a blue Calvin Klein gown that was covered in sequins, and featured daring cut-outs on the side, while also allowing her to flash plenty of cleavage thanks to a low-cut neckline.Selena, whose hair was styled in soft curls, picked nude lipstick and dramatic smoky eye make-up, while Taylor kept her eye make-up toned down but wore her signature red lipstick.

Perhaps the most memorable look of the evening was Lady Gaga's. The 29-year-old was performing a tribute to David Bowie during the ceremony, and also paid homage to the late singer with her outfit.
