Has Harry Styles left the Single's Club? Are they (Harry Styles and Cara Delevingne) having hots for each other, again?

The "One Direction" star Harry Styles has reportedly expressed his love for Cara Delevingne many times in the past. Recently, they went out on a theatre date on Aug. 31.

It seems like Styles has revived his love with Delevingne. They both are quite busy with their careers, but sources tell Styles "genuinely likes Cara a lot." In fact, he took out time and went to see "The Book of Mormon" musical in London's West End, as per Hollywood Life.

Styles and Delevingne have been keeping their relationship a low-key affair, but after looking at the way they are heading, we can say that they can be together, forever.

"They have great chemistry. Sure, they've always agreed to keep things super casual and private because of their crazy worlds, but Harry genuinely likes Cara a lot - he has done ever since they met three years ago," a source says to Look magazine.

The feeling is mutual, Delevingne also likes Harry, but given her ladies man image, she wonders how to go about it.

"They've actually had an on/off thing going all this time when they're in the same city, but they've never had the chance to give a real relationship a shot," the source tells. "I can't imagine she wants to join the list of women who have been Harry'd."

English model Cara Delevingne wants to take each step cautiously as she doesn't wish to get hurt. But, Styles seems to be absolutely in love with her. Of course he might profess his love for her - and he has done that on many occasions - but she's heard it all before," the source continues.

"He said that to her just a month before he went public with Taylor [Swift], so I imagine she's learned her lesson."

We believe that they should relax and give love a second chance before any one of them jumps to a conclusion.

If we look back, Styles has always loved the way Delevingne has been. His love for the model has never cooled down, even after Delevingne's model agency Storm asked her to leave him for good in 2011.

"Harry's not used to being dumped and he hasn't got Cara out of his system," a source revealed to Yahoo! OMG! back in 2012.

"Harry's still smitten by her upmarket background, her fun lifestyle and her socialite world. It's a different world from Harry's and he wants to know what it's like from the inside. The man usually gets the girl but this one has eluded Harry and he hasn't given up."

"Harry even thinks she could be the one. He's keeping things low-key, but his dad has given his approval and thinks Cara is great. Harry sent Cara flowers and a present before she hit the catwalk for Victoria's Secret, because it was her debut. He texted her all the way through, telling her how gorgeous and wonderful she looked."

Styles' determination to be with Delevingne is remarkable, and we wish him good luck!
