The 'Lullaby' hitmaker wed the former 'Made In Chelsea' star in 2013 but insists he unloads all of his negative feelings onto a therapist rather than his wife as that's ''not what [their] relationship is about''.
When asked if he feels safer since tying the knot, he explained: ''Kind of, but I don't rely on her to fix my problems, that's not what our relationship is about. If I need help I need to find the right person to give me that help.
''I do see a therapist, and that's one of the best things I've done, but that's recent, it's not something I done a long time ago, that's in the last year really. I don't think you should rely on your partner to fix those problems. You should be there to support each other.''
And the 31-year-old rapper - real name Stephen Manderson - also admitted he used to feign a physical illness in his younger days as his anxiety stopped him from going to school.
Speaking on ITV's Loose Women, he added: ''I've suffered with depression, and anxiety's something that I've had since I was a baby. I used to say to my nan, 'Nan, I've got a belly ache', which meant I ended up taking a lot of time off school with doctors putting cameras down my neck looking for a physical ailment that wasn't there, but I didn't have the tools to say I'm anxious.''
He also slapped a jet-lagged Taylor Hawkins.
The acclaimed performer had just cancelled touring due to a battle with cancer.
