It's time to meet the new Christopher Dollanganger.

Pretty Little Liars actor Wyatt Nash is set to replace Mason Dye in Lifetime's highly anticipated Flowers in the Attic sequel, E! News has exclusively learned.

Nash will take over the male lead role of Christopher Dollanganger in Petals on the Wind, which is set 10 years after the original film.

It was recently announced that Rose McIver, best known as Tinker Bell on Once Upon a Time, will take over the role of Cathy Dollanganger, Christopher's sister-love, for Mad Men's Kiernan Shipka.

Aside from playing Nigel, Cece's (Vanessa Ray) co-conspirator earlier this season on ABC Family's Pretty Little Liars, Nash has also appeared on Mistresses, Hollywood Heights and 1600 Penn.

Reprising their roles from the original film, which locked in 6.1 million viewers for Lifetime, the network's most-watched original movie since 2012, are Ellen Burstyn as Olivia Foxworth, the religious grandmother; Heather Graham as Corrine, Cathy and Christopher's horror of a mother; and Orphan Black's Dylan Bruce as Paul, Corinne's lawyer husband. Van Helsing's Will Kemp will join the movie as the dancer Julian, Cathy's abusive lover.

Petals on the Wind  begins filming on Tuesday, Feb. 25 in Los Angeles.

Screenwriter Kayla Alpert, who also wrote the first film, describes Lifetime's adaptation of Petals—the second book in V.C. Andrews' popular Dollanganger book series—as "a very juicy and compelling revenge drama."
