“This Is Us” star Chrissy Metz kicked off WrapWomen’s Power Women Summit Thursday night with a live performance of the original song “I’m Standing With You,” accompanied by Diane Warren on guitar and a girls choir. The song was written by Warren for the feature film “Breakthrough,” which starred Metz. Watch the duo perform in the video above. Following her opening number, Metz sat down with TheWrap founder and editor in chief Sharon Waxman to talk about her experiences in the entertainment industry, including whether or not she feels pressure to lose weight from those who still value thin talent. Readers can find her answer here. WrapWomen’s Power Women Summit, held at the Fairmont Miramar Hotel in Santa Monica on Thursday and Friday, brings together 1,500 of the most influential women from the entertainment, media and technology industries, making it the largest gathering of its kind.

The summit will provide two days of education, mentorship, workshops and networking.
