John Cena is keeping his dating habits to himself

When asked by ‘Entertainment Tonight’ if there’s any hope of the duo getting back together, he said: “That's information for me. That’s a good question. I appreciate you asking. You're probably worried about me. What does he do in his spare time? I'm keeping busy, man. I'm keeping busy. That’s information I'm gonna keep with me.”

Last month, however, 34-year-old Nikki wasn’t so coy about her love life, as she said she’s “single but not ready for mingling yet.”

She added: "I think it's happiness, and just fully being happy and that's what I want. I just feel like I'm at that age where I'm discovering who I really am and what I want out of life and just, like, independence. It is scary and you do have these moments of like, 'What am I doing?' - and fear. I just kind of am liking the challenge."

The brunette beauty thinks it's important she learns how to love herself before she dates again.

She explained: "It was quite a journey to really love myself. But I think when you go through so much, I don't want to say hate but criticism, it makes you do two things: You can even go in a way to please other people or you can take a good look at yourself and go, 'This is who I am. This is how I was made and I'm going to love it.

And I'm just going to shine that confidence through.' You're better in a relationship when you fully have that self-love and love yourself and know who you are because then you're just so confident in that relationship."

And although the pair are no longer together, Nikki recently revealed the pair are still close friends who share an "amazing connection”.

She said: "We are [the best of friends] I think it's when you have an amazing connection with someone and you just stay friends.”
