Meghan Markle's 'Suits' co-star Patrick J Adams has banned himeseld from posting pictures of her on social media after one of his uploads sparked rumours of a romance between the pair.

The 36-year-old actor - who portrays Mike Ross in the popular American show - has revealed he "overthinks" everything he uploads on social media because he is fearful of the "ramifications", especially after the reaction he received to an old photograph he posted that captured the brunette beauty kissing his cheek. 

Speaking to Esquire about the 36-year-old actress - who is currently dating Prince Harry -, the star said: "I'm not good at it, I overthink every post that I put out and the ramifications and who'll be listening and how it'll be received. 

"I posted this old photo I had found of Meghan and I on set. I went to bed, and woke up in the morning and realised 'Oh, yeah. I live in a world where you can't post things about Meghan.' 

"I had this onslaught of people retweeting the thing, people thinking it was a recent picture, and I just thought, 'What the hell is going on?'

"It was such an innocent moment of sentimentality that was twisted into something totally different. It made me feel like... why put myself through this?" 

But Patrick has revealed there was nothing "lurid" behind the post as he considers Meghan to be more like a sibling.

The Canadian-born hunk - who married Troian Bellisario last year - continued: "We're like brother and sister, it's not like it was lurid or anything, but it just became a story that people wanted to talk about."
