Love can be unpredictable, especially in Hollywood. While some actors fall for their co-stars while playing romantic partners, others find unexpected chemistry with someone who was supposed to be their on-screen sibling.

Here are the 10 celebrity pairs who blurred the lines between reel and real life.

Michael C. Hall and Jennifer Carpenter

They played adoptive siblings Dexter and Debra Morgan on Dexter, but tied the knot in 2008 after falling in love off-screen.

Their marriage ended in 2010, yet they remained close friends and even reunited for Dexter: New Blood.

Chris Pratt and Emily VanCamp

The Everwood stars portrayed brother and sister Bright and Amy Abbott, but dated in real life for three years.

Pratt once joked that fans found their romance “a little creepy,” but the two laughed it off.

Blake Lively and Penn Badgley

Gossip Girl characters are step-siblings in the show, but their real-life romance blossomed behind the scenes.

They dated from 2007 to 2010, keeping their breakup private until after filming ended.

Lily Collins and Jamie Campbell Bower

They played love interests-turned-siblings in The Mortal Instruments: City of Bones and continued dating on and off until 2018. Fans adored their chemistry both on and off screen.

Lauren Graham and Peter Krause

The Parenthood stars portrayed siblings Sarah and Adam Braverman, but developed a quiet real-life romance that lasted over a decade before splitting in 2021.

Matthew Broderick and Jennifer Grey

They acted as feuding siblings in Ferris Bueller’s Day Off, but secretly dated after filming. Their relationship ended after a tragic car accident during a trip to Ireland.

Drew Barrymore and David Arquette

They played siblings in Never Been Kissed, but according to Arquette, the two dated years before filming, calling Barrymore “one of the sweetest people in Hollywood.”

Bill Hader and Anna Kendrick

As the Kringle siblings in Disney’s Noelle, their chemistry carried off-screen. The pair quietly dated for nearly two years before splitting in 2022.

Emily VanCamp and Dave Annable

After dating her Everwood co-star, VanCamp sparked another romance with her Brothers & Sisters castmate. Producers even rewrote the show to avoid awkward storylines.

Tom Hanks and Rita Wilson

The longtime couple portrayed siblings in Sleepless in Seattle, five years after marrying in real life.
