The 20-year-old model says she was glad to have elder sister Gigi with her when she first time walked the runway at the Victoria's Secret fashion show, reported Femalefirst.
"It's amazing. She's really my comfort zone and my comfort blanket, so to be able turn around and to be able to talk to her, it really grounds me and makes me a little less nervous to have my best friend with me.
"She'll always give me her honest opinion about everything - she watched my rehearsal yesterday. She's always right there with me, so it calms me a little bit... I'm just trying to get out there and be confident and work it as hard as I possibly can," she said.
"I couldn't sleep - I was so excited last night and kind of jet lagged. So, once I fell asleep, I think I was asleep and out cold. I didn't know how to feel this morning, I was still nervous, but now that I'm here, I'm excited.
