Mae Whitman, Miles Heizer Kiss? 'Parenthood' Siblings Kiss On Instagram

Are Parenthood co-stars Mae Whitman and Miles Heizer more than just friends?

Quite a few Parenthood fans and critics may have asked themselves that question after Mae Whitman posted a picture of the TV siblings kissing for "National Kiss Day" on June 19.

The picture, which was posted on Mae's official Instagram page, was accompanied with a caption that made a minor change to the name of the international day of kissing.

"Happy National Kiss Your Brother Day everyone!!!"

Miles Heizer shared the same photo on his own Instagram page with a slightly different caption.

"Ruining anyone who watched parenthood's national kissing day."
Quite a few people have responded via Twitter to the kissing photo of Miles Heizer and Mae Whitman. Some did not like the idea of them kissing - especially since they played brother and sister on the hit NBC series, Parenthood for six seasons.However, there were a lot more people that seemed to be okay with it - going as far as encouraging the two BFFs to seriously consider taking their friendship to the next level.In recent years, Mae Whitman and Miles Heizer have made their off-screen friendship clear to the rest of the world.Mae Whitman spoke openly about her friendship with her TV brother and real-life roommate in a March 2013 interview with BuzzFeed.
"We're definitely unusually close, just as far as human beings go. Miles is definitely my best friend."
Whether Mae and Miles will ever be more than friends is not clear - only time will tell.

However, if Mae Whitman and Miles Heizer do decide to leave the "Friend Zone," they would not be the only set of Parenthood TV siblings with a real-life romance. Actors Peter Krause and Lauren Graham (who played Adam and Sarah Braverman) first started dating shortly after they met on the Parenthood set in 2010.
