The 26-year-old model, who recently split from the 'Loyal' hitmaker after it emerged he'd fathered a nine-month-old daughter, Royal, with their mutual friend Nia Amey last year, admits she stuck by him in the past because she was desperate to help him get his life back on track.

In a clip from her upcoming interview with life coach Iyanla Vanzant for OWN series 'Iyanla: Fix My Life', she said: "I wanted to love him because that's what he needs. Love."

Asked how she knows what the 25-year-old singer needs, she replied: "I know what he needs after four years, I know."

Karrueche also admits she initially didn't want to believe Chris was cheating on her with on-again, off-again girlfriend Rihanna in 2013, whom he first split from in 2009 after he violently assaulted her.

She said: "I was under the impression that it was a friend-type of...not a friend but it wasn't what it became to be.

"I knew, but I didn't want to believe it. Huge mistake! Huge."

While Karrueche discusses intimate details about her time with Chris on the show, which will air on OWN on Saturday (28.03.15) at 8pm, she claims she has "learned the hard way" not to share her emotions on social media.

She said: "It's nobody's business but you and the person or just you yourself, and that again allows everybody to, it leaves an open space for everybody to say what they want and have an opinion. I've learned it a few times, but I've learned it the hard way."
