"Game of Thrones" is one TV's hottest shows right now, so fans are doing whatever they can to avoid spoilers.

<span style="line-height: 1.5em;">If that's the case, fans may want to stay away from actress Lena Headey's Instagram account.</span>

Headey, who plays Queen Cersei Lannister on the series, has been posting photos that many fans see as potential spoilers.

<span style="line-height: 1.5em;">For example, </span><span style="line-height: 1.5em;">Sunday night's episode involved a brutal battle between <span>Oberyn "The Red Viper" Martell</span> (Pedro Pascal) and <span>Ser Gregor Clegane (</span><span>Haf&thorn;ór Júlíus Björnsson</span><span>)</span>.</span>

<span style="line-height: 1.5em;">It culminated in Oberyn getting his eyes gouged out.</span><span style="line-height: 1.5em;"> </span>

<span style="line-height: 1.5em;"><span><img src="http://static5.businessinsider.com/image/538e34cd6bb3f78c497542c5/red-viper,-eyes,-mountain-game-of-thrones.gif" border="0" alt="Red Viper, eyes, Mountain game of thrones" />Many fans think one of Headey's previous Instagrams looks awfully similar to the way Pascal's character met his demise.</span></span>

<span style="line-height: 1.5em;">Before the episode aired, Headey posted this photo jokingly gouging out fellow cast member Pedro Pascal's eyes two months ago.</span>

<span style="line-height: 1.5em;">The image is from a feature in Hunger Magazine; however, fans noted the similarity was uncanny.</span>

<span style="line-height: 1.5em;">Fans have also been speculating the meaning of another one of Headey's photo posted a month ago. The photo found below is of stones making up a heart shape with the caption "my stone heart."</span>

Warning: MAJOR potential spoiler ahead.

Many fans suspect this as a spoiler for the return of Catelyn Stark (Michelle Fairley) who becomes known as "Lady Stoneheart" in the books after she's brought back to life.

<span style="line-height: 1.5em;"><img src="http://static2.businessinsider.com/image/538e1b3c6bb3f76366859ef0-1200-600/game-of-thrones-catherine-stark-red-wedding-1.jpg" border="0" alt="game of thrones catherine stark red wedding" />However, not every cast member's Instagram spoils the show.</span>

Here's a fun off set photo from Pedro Pascal's account showing the very different sizes of Pascal and Haf&thorn;ór Júlíus Björnsson, who plays The Mountain on the series.
