With their recent social media posts, singers Ricky Martin and Pablo Alborán have fueled rumors that they may be in a relationship.

On Sunday Dec. 6, Martin shared a photo of himself in bed and laying on white sheets, on Instagram. The Puerto Rican superstar captioned the photo with a simple "Good morning."

Less than an hour earlier, Alborán shared an almost identical image of himself laying on similar white sheets and captioned it with the hashtag "#sunday."

Rumors of Martin and Alborán being romantically involved have been circulating for quite some time.

According to Televisa Espectaculos, about a year ago Alborán denied that he and Martin were dating and shared his distaste with being asked about his personal life.

"It's sad that just for posting a photo you get asked who is sleeping on your bed. It is a question that shouldn't be asked in this century. It's embarrassing and sad," said the Spanish singer.

Since choosing to reveal that he is gay, Martin hasn't been public about his dating life but has been vocal about supporting LGBT rights.

Also vocal about the LGBT community is social media star Tyley Oakley, who recently discussed Martin in an interview with HuffPost Live. 

Oakley explained how his videos helped the Puerto Rican superstar come out. He recalls waking up to a tweet from Martin on National Coming Out Day, in 2011, that contained a link to one of Oakley's videos.

In the tweet, Martin revealed that the video helped him make an important decision in his life, the decision to come out.

"I was just blown away because to me, I was just making videos... but there was a moment when it kind of clicked for me that you never know who is watching and you never know who you can impact and you never know the ripple effect that can happen, just by being yourself," he said.
