As "Pretty Little Liars" season 4 heads towards the finale, the sudden appearance of a scandalous photo on Instagram has all attention on a former cast member—Tyler Blackburn.

After the recent cancellation of "Ravenswood," it appears actor Tyler Blackburn is vacationing in Fiji, which includes activities like yoga…and skinny dipping.

The "Pretty Little Liars" alum posted a photo on Instagram which features a little more of the actor than fans could've expected.

Now that Tyler Blackburn is a free agent again, it's entirely possible that Caleb might be returning to Rosewood as "Pretty Little Liars" continues season 4 and into season 5.

"On ward and upwards. You never know when you'll see me on screen again," tweets Blackburn on February 16.

Meanwhile, "Pretty Little Liars" season 4 is definitely heating up as Spencer's downward spiral continues.

Spoilers confirm that things will get worse for Troian Bellisario's character before the season 4 finale.

"With Spencer, there are big gaping holes in her memory which will serve as incredibly difficult realizations about what she may have done. There are revelations and realizations that she maybe had confrontations or ugly encounters that she may have blotted out and can't remember," says executive producer Oliver goldstick to E! Online.

"But there are people that are going to remind her, you better believe it! Somebody was taking notes that summer."
