The couple shocked the world almost two years ago when they announced they had decided to split following six years of dating, but it's thought the pair haven't ruled out a reconciliation in the future because they are still "super close" and speak regularly.

A source to People magazine: "They're super, super close and have a crazy love for each other. They're extremely close friends but there's always potential they could give a romantic relationship another try. She's very vocal about the fact that he is the love of her life. A lot of their issues had to do with their age difference, but she's matured a lot even in the past year or so. At first it was really fun for her to be single and date around, but now she's starting to see that the grass isn't always greener."

And the pair set tongues wagging earlier this month when they were spotted enjoying a lunch date together at Sol y Luna in Tarzana, California.

However, the 25-year-old singer previously said she has some "issues" that she needs to conquer before she can get back into a relationship with the 38-year-old actor.

She said at the time: "The sparks never faded but there are issues that I haven't conquered yet that I know I won't conquer if I'm relying on somebody else to take care of the loneliness. I just wasn't ready and there was so much in my life that I hadn't explored yet ... That was one of the reasons why we broke up because I've never been alone. It had nothing to do with falling out of love, we decided together we just probably are better as friends ... I do have moments where it's late at night and I'm lonely and I wonder if I made the right decision because love is a gamble. I don't know if I'll lose him for the rest of my life. I think my heart is always with Wilmer, I think it was with Wilmer, I think it is with Wilmer, I think it will be. Because you don't share six years with somebody and not give them a piece of your heart and vice versa."
