Purple reign! Lily Collins looks majestic in floor-length lavender dress as she steals the show at Love, Rosie premiere in Rome
Her dad may be rock 'n' roll royalty, but Lily Collins stole the crown in the style stakes as she took to the red carpet in Rome over the weekend.
The stunning 25-year-old - whose father is Genesis legend Phil - was in the Italian capital on Sunday to promote her latest film, Love Rosie.
The movie premiere was part of the schedule at the ninth Rome Film Festival and Lily ensured she gave the glamorous natives a run for their money in a showstealing purple Elie Saab gown.

Lily worked the princess prom dresses - which consists of purple, lavender and purple hues as she posed for photographers but have chosen dramatic make-up in similar shades.
To keep your hair simple, the actress went for a chic wavy retro look and was joined on the red carpet with the film's director Christian Ditter and her male co-star Sam Claflin, who looked handsome in a Dolce and Gabbana suit.

The trio caused a stir among fans gathered on the sidelines to get a glimpse of the stars, and Lily sure she made time for his followers by spending time signing autographs and posing for selfies.
The new movie is set to be Lily's first big romantic comedy in which she plays Rosie, a girl who keeps coming close to falling in love with her childhood pal, played by Sam.

The project is adapted from the book Where Rainbows End by Cecelia Ahern, Irish author, whose previous novels include PS, I Love You, which became a box office sensation starring Hillary Swank and Gerard Butler in 2007.
And because of Lily having to have a special chemistry with her leading man on screen, she was happy when Sam came in during the audition process - because they already had so much in common.

During a recent photoshoot for The Edition, Net-a-Porter weekly fashion glossy, she explained: "We were forced into a room together for a" chemistry test "because the director wanted to get a sense of how we would get on
'There had been so many near attempts of us meeting and working together before, and we have so many mutual friends, that it felt right immediately.'
The movie, which also marks the major acting debut of model Suki Waterhouse, hits cinemas on October 22.
