The 'Hollaback Girl' hitmaker regularly wears her customised Vans skater shoes with her country musician beau's portrait emblazoned on them, and while the 41-year-old singer thought it was a sweet idea at first, he wishes she wouldn't wear them.
He confessed: ''I don't know where she got those damn things.
''I remember when she got them though.
''They shipped them to the house and I didn't even know what to think. I was like 'What is that?' and she goes 'Aren't they cute?'
''I was like 'I don't know how to answer that. That's my face.'
To me, they're not cute but I guess the idea [is].
''She wears them all the time though, it's funny. She walks around with my face.''
Blake - who has been dating the No Doubt frontwoman since 2015 - also revealed that his 48-year-old girlfriend gets annoyed when people say she copied his ''camo-wearing'' fad as she has worn camouflage items since she was a teenager.
Speaking to PeopleStyle, Blake - who is launching his own BS Clothing range at Macy's department store in New York - said: ''It's funny because when she and I started seeing each other the pictures of us would come out and she'd be wearing camo and the headline would say 'Blake Is Rubbing Off on Gwen - She Has Camo On'.
''She's like 'What the f**k? I've been wearing camo since I was 17 years old. Here's the pictures. Why are they saying that? No, I'm the camo girl. You're copying me!'''
The 'God Gave Me You' hitmaker also claims Gwen - who has sons Kingston, 11, Zuma, nine, and Apollo, three, with her ex-husband Gavin Rossdale - steals his baseball caps on a regular basis.
He said: ''If there's one thing that Gwen has started doing that she probably didn't do before is the baseball caps that she puts on, they have a little shape to them now.
''It's probably because it's my cap she grabs and puts on. She didn't mean to.''
