Rebekah appeared on the reality TV show back in 2009 as Rodrigo Lopes.
Today a desperate Rebekah tweeted: "I'm not dead!".
"I'm so sorry", replied one Twitter user.
But previous year, the reality star admitted she was struggling to cope with the huge transition because she felt isolated.
She said: "At one point before my surgery I had to leave home, and for six months of my life I turned to prostitution".
She recently she made an appearance on ITV's Judge Rinder where she appeared to try and claim money back for a botched boob job.
Last year Rebekah spoke out about her struggles during transitioning.
"I saw that terrible thing between my legs and I started crying around the hospital saying, 'I regret, I regret.' I wanted to kill myself because it was a nightmare".
"When he took me out and introduced me to his friends, for the first time in my life, I felt like the person I was meant to be from when I was born".
She sees herself as a "modern" woman and chose Rebekah because she "loves" the name adding the surname Shelton because it is the surname of his English family who he lived with when he first came to the UK.
"It was a big step to go full time as a woman".
