kate hudson iheartradio-Kate Hudson was a real beaut at the iHeart Radio Musical Festival in Las Vegas Friday.

The 34-year-old touched down in Sin City to support fiance Matthew Bellamy who is performing there with his band, Muse. Hudson was spotted wearing a short purple satin romper that had a cut-out at her stomach. The fresh-faced actress paired the look with some red pumps.

Hudson, who gave birth to baby Bingham back in July 2011, was a presenter at the big show. She arrived on the red carpet in a black, low-cut fitted jumpsuit, a leather belt and peep-toe shoes.
