Over the weekend Shailene Woodley and Ansel Elgort's movie "The Fault in Our Stars" opened up to a great weekend taking in a cool $48 million.

While fans were brought to tears we're sure even more would have been shed if they knew the stars of the film attended the movie with them.

According to Just Jared, Elgort was more than happy to share a photo of himself and a disguised Woodley on Instagram. The actress covered her short pixie cut with a curly wig for a fun night out with her cast boyfriend.

Attached to the photo was the caption, "Shai's amazing disguise to go see #tfios last night without causing a scene!" The actor who plays Gus in the film also took to Twitter to tweet about his costar's tricky ways.

He revealed, "Shai is bringing her own popcorn to #tfios hahahaha. So bootleg."

When she isn't sneaking into theaters, Shailene Woodley is busy falling in love and starring alongside amazing and handsome leading men. She told the Daily Mail about one of her past romances.

The 22-year-old revealed, "Age can't define love. I was in a relationship that was very intense when I was 17."

She added, "I definitely had those feelings of lust and infatuation. The love that I experienced with him was true in that moment. As a teenager you're not jaded, you are free to be vulnerable because you're not putting up big walls."

The former ABC Family star also talked about her joy working with Ansel Elgort. She revealed, "We became really close on 'Divergent.' It was cold filming in Chicago; it was a hard shoot and he was a really beautiful light, literally.

"Going straight from that film to 'The Fault In Our Stars' was such a gift, because we were able to be comfortable around each other and bring our natural chemistry to the screen," adding, "It was awesome working with Ansel. He brought a lot of light to my life."

However, the young starlet couldn't help but gush about what a good time she had with Theo James on set as well.

Shailene Woodley confessed, "He makes me laugh really loud. English humour is perverted, raunchy and dry."
