The actress is rising up in Hollywood, but many still don't know that much about her life.
Lily Collins, the daughter of Phil Collins, is 29 years old, and has carved out a successful career for herself in the entertainment industry.
As reported by The Sun, Lily is a British-American actress, model and writer.
In recent years she has appeared in a number of high profile films, such as Blind Side, Priest, Mirror Mirror, and The Mortal Instruments: City of Bones. Her performance in Netflix film To The Bone has also won her high praise.
In previous years, the actress has been linked romantically to Taylor Lautner, Zac Efron, and Jamie Campbell Bower. More recently, she was seen on a romantic getaway to Italy with classmate Jason Vahn.
The pair have not been seen together since though, and some believe she is after One Direction singer Niall Horan.
The actress has previously suffered from an eating disorder, and admitted that she was very nervous about having to lose weight to play an anorexic for To The Bone. She was closely supervised during filming as a result.
The flick first premiered at the Cannes Film Festival In 2017, and Lily felt it was "informative and very impactful."
When speaking about her eating disorder and the effect the film had on her, she explained that it was the first time she had taken on a role of its kind.
"I have been very vocal in the past about my own eating disorders and it's become quite taboo to talk about, even though the fact it's becoming more and more prevalent in today's youth with men and women," she said.
In March 2017, Lily spoke out about how her relationship with her father had impacted her early life, and how she felt he had not lived up to her expectations.
To Lily, he was never a present and supportive father, and didn't fulfil his in her life, especially as he had always lived on a different continent to her.
As a result, she felt that their relationship was a contributing factor to many of her deepest insecurities.
The letter appeared in her book, Unfiltered: No Shame, No Regrets, Just Me, which aims to help teenage girls express themselves.
