The picture shows her posing with Mark Wright at Ships and Giggles, where she helped with celeb appearances as part of her job, and now her former boss has shared what she was like when she worked there from 2012 to 2014.

Bar owner Andy Macdonald, 38, said Ekin-Su was known as Susie Hayzel to pals back then, and although suprised at the name change, says it was “a comical but smart move.”
Andy said: "For weeks, I kept getting these messages from people saying that a girl called Ekin-Su was working for me.
"It was getting to the point where I was getting pissed of by all these messages about her, and I didn't know who this Ekin-Su was.
"One time it was on TV so I just thought 'right that's it' and had a look, I hadn't seen any posts because I don't follow the show, and there she was.
"I just laughed and went 'that's Susie bloody Hayzel'...I couldn't believe it.
"I have never known her other that Susie Hayzel, and I'm still friends with Susie Hayzel on Facebook."
Andy also believed the Love Island star was half Irish, and had no idea that she was Turkish after she entered the Miss Asia Pacific World pageant as Miss Ireland.
He commented: "I asked her how she won Miss Ireland as it's another country.
"She was like 'what do you mean it's another country? Isn't it part of England?' and I was like oh my god Susie, oh no."
Ekin-Su was always one of Andy's 'go to girls' and often worked with celebrities, including Mark Wright.
Andy said: "She was flirty but she was never creepy with it - she was always pleasant, always happy, always smiling.
"She always made celebrities feel comfortable and she would always look after them and take photos with them.
"She was class, I don't have a bad word to say about her."
Whilst Ekin-Su worked at the pub, she also starred in a student documentary called 'Lancshore', in which she once offended Andy.
He explained: "Everyone was saying about going to Ships and Giggles, and I didn't not care how amateur this production was, but Susie turned around and went 'we always go to those places, lets go somewhere different.
"I was furious, I messaged her asking how dare she do this and she just said it was filmed before I worked there."
Her former boss didn't watch the Love Island final, but he always knew she would be successful.
Andy added: "She was always ambitious and never held back with what she did, she always said she would make something of herself.
"She always had that attitude and that personality.
"She would say the most silliest things that you couldn't image, but she was extremely smart at the same time."
