'Grey's Anatomy' stars Chyler Leigh, Justin Chambers reunite: See the photo

Chyler Leigh and Justin Chambers got the hearts of "Grey's Anatomy" fans racing -- all with a single selfie.

The actors recently took to Instagram with a photo of them having a mini reunion and referencing each other's characters from the long-running ABC primetime medical drama in the captions.

"KAREV… forever charming ❤️ @officialjustinchambers," Leigh wrote alongside her post.

For his post, Chambers wrote, "Being with LEXIE is HEAVENLY 🪽❤️ @chy_leigh."

Chambers is one of the original "Grey's Anatomy" cast members, playing Alex Karev from the show's very beginning in 2005.

His character departed midway through season 16 -- in the milestone 350th episode -- as he left Seattle to start his life with former flame Izzie Stevens (Katherine Heigl) and their children.

Leigh played Lexie Grey -- the little sister of the show's central character, Meredith Grey (Ellen Pompeo) -- from season 3 to season 8.

Despite her tragic death on the show in a tragic plane crash, Leigh returned for a cameo during season 17 during a dream sequence while Meredith was in a COVID-induced coma.

"Grey's Anatomy" has been renewed for a landmark 21st season .
