On-set romances between Hollywood co-stars aren't exactly uncommon, but these relationships
don't usually involve actors who play siblings.
These are just some of your favorite celebs who just happened to fall for their on-screen
brother or sister.
Peter Krause and Lauren Graham played brother and sister Adam and Sarah Braverman on Parenthood
from 2010 to 2015.
"You need to find her."
"Who?"
"Your daughter."
"That's your advice?
Thanks, big brother!"
Since then, they've been a real-life couple, and they're almost too cute to stand.
Krause told Live!
With Kelly and Ryan that they kept their relationship "pretty quiet" in the beginning but eventually
went public when it got serious.
Krause also revealed that Graham tried to date him almost 15 years earlier when they
both guest-starred on Caroline in the City, but he didn't pick up on her flirting.
He explained:
"She had me move some furniture into her apartment for her back then.
She had got some thing.
I didn't catch the signal."
Graham has been forthcoming about their romance, which is still going strong to date.
She wrote in her memoir, Talking as Fast as I Can:
Talk about an '80s dream team!
Jennifer Grey and Matthew Broderick, who starred as siblings Jeanie and Ferris Bueller in Ferris
Bueller's Day Off, were a cute couple off the big screen.
Unfortunately, their relationship was marred by tragedy.
According to People, while vacationing together in Ireland in 1987, Grey and Broderick, who
was behind the wheel, were in a car accident that left them both injured and that killed
the occupants of another vehicle - a 28-year-old woman and her 63-year-old mother.
Grey later admitted that she was never the same after the accident, which occurred just
days before the opening of Dirty Dancing.
She told People:
Michael C. Hall and Jennifer Carpenter starred as incestuous foster siblings Dexter and Deb
on Dexter - and they fell so in love off-set that they actually got married.
"I mean, it's one thing to be in love with your brother, but it is a whole 'nother level
to be in love with your brother who's a g------ f------ serial killer."
Carpenter and Hall tied the knot in December 2008, People reported, but the bliss didn't
last long.
Hall and Carpenter separated in August 2010 and divorced in December 2011.
The exes were relatively amicable and continued to work together after their split.
People reported that they even frequently went out for platonic meet-ups.
In 2013, Carpenter teared up at a Dexter fan event when asked about working with her ex.
According to Us Weekly, she admitted:
Maggie Grace and Ian Somerhalder played step-siblings Shannon and Boone on Lost, and after being
killed off the series, they quietly dated in real life from 2006 to 2007.
They kept their romance mostly under wraps while they were together, but they spoke fondly
of one another after their split.
In January 2015, Grace told New You magazine:
Though the pair appeared cozy at a Lost reunion in 2014, they are simply pals.
Somerhalder married Twilight actress Nikki Reed in April 2015.
The Brady Bunch stars Barry Williams and Maureen McCormick, who starred as siblings Greg and
Marcia Brady, respectively, had the hots for one another on the set of the show.
Sparks didn't fly immediately, as filming began when McCormick was 12 to Williams' 14,
but eventually the two actors did, in fact, begin canoodling.
In her memoir, Here's The Story: Surviving Marcia Brady and Finding My True Voice, McCormick
described her first kiss with Williams as "long, passionate and deep," but she also
added:
The New York Daily News reported that she even admitted she would have lost her virginity
to Williams if his parents hadn't walked in on them getting hot and heavy at his house.
She also revealed a scandalous secret about The Brady Bunch episode in which Marcia and
Greg bicker about the attic bedroom.
She and Williams supposedly couldn't keep their hands off of each other in that very
bed.
