Rita Ora will celebrate her 25th birthday on Thursday, 26 November. The British singer and actress, who gained fame with her debut album "Ora" in 2012, has also had a stint in Hollywood with films like "Fast & Furious 6", "Southpaw" and "Fifty Shades of Grey" among others.

The "X-Factor" judge has had a pretty good year so far with hits "Black Widow" and "Body on Me" doing really well on the charts. Not just this, she was even noticed for her performance in "Fifty Shades of Grey" as Mia Grey and as Maria Escobar in "Southpaw". Well, it's not surprising that Rita decided to bring in her birthday a bit early this year.

The singer was spotted heading to celebrity culinary hotspot Sexy Fish for her early birthday bash on 24 November with friends, including rumoured boyfriend Lewis Hamilton. But the fans are speculating if she will have another quiet celebration with ex-boyfriend DJ Calvin Harris on her birthday?

Rita as we know has dated Rob Kardashian and Bruno Mars in the past and very recently broke up with Richard Hilfiger. But, her most-talked about relationship was with DJ Calvin Harris, with whom she broke up in 2014.

Though both of them mutually decided to split and even announced their split on social media, the "Rip" singer did confess that she was upset.

In her recent interview, Rita Ora had said: "There was a reason why I split up with him. [...] It was more of a thing where I was in awe. I was at that point in my relationship where I felt he could do no wrong. I thought he had my back and that he'd never steer me wrong. But then "I Will Never Let You Down" came out, and everything started to go a bit weird. I don't know if it was because business was mixed with personal or what."

And now, we know that the Scottish DJ has moved on and is dating Taylor Swift. But, fans wonder if Rita Ora still hopes to celebrate her birthday with her ex-boyfriend. And since Taylor-Calvin break-up rumours too have been running wild, is it possible that Rita Ora's birthday reunion will bring them both close again?

Now, Calvin Harris and Rita Ora fans can only hope that this birthday reunion happens.
