Colourful, bold fashion dominated the iHeart Radio Music Awards red carpet on Sunday night, but it was Taylor Swift - wearing a black sequinned mini dress by designer Kaufmanfranco - who stole the show that evening. Not only did the 25-year-old singer take home three awards including the coveted Artist of the Year, but she floored fans with an impressive performance alongside music icon Madonna.

Likewise, the Shake It Off singer dazzled on the red carpet as she arrived for the glitzy cut-out dress, which gave fans glimpses of her enviably toned figure.

Taylor was spotted hanging out with fellow hit-maker Justin Timberlake throughout the evening, and the pair caused a social media meltdown after Taylor was announced as the recipient of the Best Lyrics trophy for her song Blank Space.

While the blonde beauty had a pretend freak out, mock-screaming with joy, Justin - who was sat beside her - jumped out of his seat and headed towards the stage pretending to accept the award himself. He dropped the act, though, sending Taylor on her way with a hug to pick up the award from Madonna.

Bajan beauty Rihanna also made heads turn at the ceremony with a jaw-dropping performance, where she showed off her fashion-forward style credentials in a head-to-toe outfit by Versace. The 27-year-old showed off her curves in a black mini dress which she paired with an oversized neon green fur coat and thigh-high green leather boots for a fierce look.

Meanwhile, Pitch Perfect star Brittany Snow wowed on the red carpet in a chic white knee-length dress with cut-out detail, wearing her glossy locks in a long side braid. She was not the only star to dazzle in white for the event. Modern Family star Ariel Winter also stunned in a chic shift dress which she paired with a colourful box clutch bag and patterned stilettos.
