All eyes were on Demi Lovato yesterday as she made her stunning entrance on the red carpet at ROC NATION’s exclusive pre-Grammy brunch held at Owlwood Estate in Beverly Hills, CA. The 24-year-old singer wore a matching white ensemble of long skirt and bustier crop top, showing off her rock-solid abs. Lovato has a lot to celebrate this weekend as her album, “Confident”, is nominated for Best Pop Vocal Album and is her first-ever Grammy nom.Lovato was joined at the exclusive event by Nick Jonas, her former co-star and tour mate. Nick took to Instagram later and posted a photo of the duo together from the event with the congratulatory caption: “Proud of this girl. Grammy nominated and about to absolutely blow people’s minds again this year with her performance. #safehouse.”
