Not everyone agreed with People Magazine's choice of Blake Shelton as Sexiest Man Alive.

But the one person who mattered did: his girlfriend Gwen Stefani, who defended the decision on Ellen on Friday.

'I feel totally responsible because he's just so not that person,' the 48-year-old told the host.

'He doesn't even like to do a photo shoot, you can never convince him to do it.'

Ellen herself had been poking light fun at the 41-year-old country singer, by employing some crude digital trickery to make it look like he was wearing just a pair of tighty whities when he performed his recent duet with Gwen on The Voice.

'He's just full of himself now,' Ellen joked, pointing out he even had his name scrawled on the back of his exposed underwear.

Gwen said the backlash over the Sexiest Man Alive title was 'chaos and craziness,' adding she couldn't believe people were taking it so seriously.

'If you think about it, what defines sexy? It really is so personal, you know what I mean?' she mused.

'For me its just that big ol' heart, and that sense of humor,' she said. 'He doesn't even take himself seriously, and hes' just such an incredible person. And that's sexy to me.'

Gwen and Blake got together in late 2015 after getting out of long-term relationships.

Personal: 'For me its just that big ol' heart, and that sense of humor,' she said. 'He doesn't even take himself seriously, and hes just such an incredible person. And that's sexy to me.'

Throwback: Ellen asked her if she thought the couple would have got together had they met at a different time in their lives — before revealing a yearbook photo of mulleted Shelton

Gwen split from husband of 14 years and father to her three children Gavin Rossdale; Blake had just left his wife of four years, Miranda Lambert.

Ellen asked her if she thought the couple would have got together had they met at a different time in their lives — before revealing a yearbook photo of mulleted Shelton.

'I feel like it actually does work out good, you should put em next to each other,' Stefani laughed as her own, far better-looking photo cropped up.

'Oh my god, that is perfect,' she declared as they juxtaposed. 'It is perfection.'
