Shay Mitchell and her "Pretty Little Liars" season 5 cast member Ian Harding have the rumors mills buzzing that the two are dating after a flirty Instagram post.

According to Hollywood Life, the costars are pretty close to one another along as well as with Ashley Benson, so it's no surprise when they post photographs of each other on their accounts however, this time around the latest snapshot shared was a bit explicit.

Although their ABC Family hit series tells a dark story full of drama, murder and lies, off screen the cast members are warm and friendly with one another.

Shay Mitchell recently took to her Instagram account to share a picture of Ian Harding with some bananas conveniently placed in his private area as he sat on a chair on set.

Attached to the picture of her costar was the caption, "... or are you just happy to see me?! @ianmharding." Both stars, 27, have been posting pictures together from the set but we are pretty sure the two are just friends.

While Harding tends to keep his love life under wraps, Mitchell has been happily dating Ryan Silverstein aka OVO Ryan aka Drake's best friend.

Besides, if anyone was to date Ian Harding from the "Pretty Little Liars" cast fans would root for his new girlfriend to be Lucy Hale who plays his love interest Aria Montgomery.

In real life the "Road Between" artist recently split from her country singer boyfriend Joel Crouse. An insider has revealed, "Lucy and Joel are done," adding, "it was hard with the distance."

The source confessed, "She's working a lot on Pretty Little Liars and on music -- she debuted at the Opry over the weekend. It got to be too much."

The actress recently debuted her new single, "Lie a Little Better," at the Grand Ole Opry on June 21st. A second source told Us Weekly that the brunette beauty simply has "no time for love right now."

Lucy Hale and Joel Crouse were first spotted out together back in April, when the two were seen attending Lakers Game in Los Angeles together.
