On April 28, Ramirez posted a message on Twitter that read: "That's a wrap for Doctor #CallieTorres #Season13 #GreysAnatomy #ThankYou all for an enriching & unforgettable #Rollercoaster ride!"

Fans of "Grey's Anatomy" and Callie Torres took notice and immediately reacted to the actress' tweet. While some concluded that Ramirez is exiting the show, others are hoping that she is going to return for Season 13.

In the meantime, speculations are running rampant. According to TV Line, Ramirez's tweet might be about her final day of work on Season 12 or she might be possibly "looking to increase negotiations leverage." The website also suggests that her message might mean that she has simply decided to end her 12-year stint in the show.

Meanwhile, Ramirez is yet to comment and confirm the news. According to the Entertainment Weekly, this is not the first time the actress has posted such a tweet. In 2014, the actress shared: "Dear @shondarhimes & all who make #GreysAnatomy @GreysABC, it's been a roller coaster ride & an honor! Thanku all! #SeasonX #SeasonZen."

In addition, the website reports that insiders have confirmed that Ramirez's contract, expiring in June, is expected to be renewed.

Currently, Ramirez's character Callie is in the middle of an important story arc. She is caught up in the custody battle of her daughter Sophia with her ex-wife Arizona. Their battle so intense has now forced their friends to take sides and make a difficult decision. The tension between the former couple continues to grow and damage their relationship further. Calzona shippers are wondering if there is still hope for Callie and Arizona.

"Grey's Anatomy" Season 12 airs Thursdays at 8:00 pm on ABC. Stay tuned for more spoilers and more.
