Sabrina Carpenter

Sabrina Carpenter set admirably simple goals as she traipsed the red carpet at Wembley Arena. "I just don't want to trip. I've been halfway down the carpet already so I'm off to a good start," she told us. The singer said she's excited about new material she's working on - but was tight-lipped about the collaborations she has lined up. "The response to [her latest single] Why has been incredible, and I've been writing my third album, so that's why I'm here. I've been in Sweden, London and Norway writing so I'm excited. "I'm definitely collaborating with some really cool people. I'm always up for changing and growth and trying new things. So you're definitely going to hear some new sounds, whatever they are, on the new album. There's already some that I'm really excited about."
