Ciara had ''clear evidence'' Future had cheated on her.

The 'I'm Out' singer recently split from her fiance, just three months after they welcomed son Future Jr. into the world, and insiders say she felt ''betrayed'' after learning he had been having an affair with his stylist and personal shopper, Tyrina Lee.

A source told Us Weekly magazine: ''She found out about the affair through multiple sources in recent weeks.

''There was clear evidence when she approached Future about the cheating. This was clearly not just a one-night thing. [She was] devastated.''

The 28-year-old beauty recently said she has a ''whole new spiritual energy'', despite the break up.

She said: ''I'm in a much more clairvoyant place in my life. So, I want to express that through my music.

''I think that when you become a mom... you don't really worry about the small stuff. I'm just way more centered. It makes you focus even more on what your goals are in life. And I just feel a whole new spiritual energy that's happening.''

Ciara plans to ''stay focused'' on her career and insists she ''can't waste time'' on things that don't matter to her.

She said: ''My son has been the best thing that has happened in my life. He has been amazing and he is truly heaven-sent. And so, I just feel all that love.

''I want to be one of those moms and women that when I look back, I know that I always stayed focused. It's about keeping your eyes on the prize. Before I had a child, I had goals. And I still have to accomplish those goals, but now that I have a child, I have more goals to accomplish. So I can't waste time. I have to go for it. It's actually pushing me harder, and forward.''
