Demi Lovato, who has just announced that she is leaving The X Factor after this season to focus on her own music, joined Kelly Rowland on the gray carpet for the show’s season finale on Thursday night in Los Angeles.

The American singer, songwriter, philanthropist, and actress donned a gold sequined V-neck dress paired with a “Smoking” tux blazer by Helmut Lang (available at Shopbop). Her Saint Laurent “Janis” platform pumps (available at Barneys) have previously been spotted on numerous celebrities, including Ariana Grande, Jennifer Lawrence, and Rosie Huntington-Whiteley.

How do you like Demi’s ensemble or her shoes, in particular? The Italian-made platform pumps in smooth calfskin leather feature pointed toes and 5 inch (125 mm) heels. The 21-year-old also wore them to another event earlier this month. Demi sported a spiked version of the same pumps and styled them with a black dress and a leather jacket when she attended the 2013 Fox Upfront Presentation in May.
