Selena Gomes attended her second annual bash to benefit UNICEF at the historic musical venue in West Hollywood. Looking rather grown-up in a nude maxi-skirt, the teen sensation flashed the flesh by wearing a belly-baring top. The star’s white t-shirt was cut to gathering the middle, leaving two areas of her stomach on show. She showed off some bright purple and blue streaks in her hair. She accessorised her look with a long chain and pendant which reached down to the belly button. She finished off the look with a pink band around her wrist to recognise the charity which helps save children’s lives. “Y’all ready for the UNICEF show tonight? See you in 5 hours,” Selena tweeted before the show. “Lots of love for the UNICEF show :),” she updated later, with a picture of some gal pals backstage including Ashley Tisdale.
