Hailee Steinfeld is ''nervous'' about sharing her work with Taylor Swift.

The 'Ten Thousand Saints' actress, who recently released her debut single, 'Love Myself,' admits she is usually hesitant about showing her close friend any of her music or acting projects even though the 'Style' hitmaker, 25, is always ''very supportive.''

The 18-year-old star said: ''I'm nervous to play her anything. I'm nervous to show her any of my movies, but yeah, she's very supportive.

''[Music] is always been something that I wanted to do. It's always been a part of my plan and it's always been a matter of when and now is when.''

Hailee is also good pals with reality TV star Kylie Jenner and attended her star-studded 18th birthday party last weekend in Los Angeles.

Asked about the lavish celebration, she told E! News: ''The party was so much fun. It was a good time. I'm still reminiscing about it. I just had a great time. I saw a lot of my friends and we did a lot of dancing.''

Meanwhile, the brunette beauty felt ''weird'' wearing a fake baby bump on the set of her new film, but couldn't resist sending pictures of it to all of her friends.

She said: ''I put it on during the fitting and I was like, 'Oh, my God, this is so weird - let me send a picture to my friends!' But then it was weird. I was then sort of uncomfortable and felt very vulnerable. It was very annoying because I could barely bend down and tie my own shoes. I felt useless. It was very interesting. I was living my very own PSA [Public Service Announcement].''
