The presenter, who previously had the Fame Monster star as a guest on the programme, claimed that the "world would be a better place" if everyone dressed like her.
She told the publication: "I love the GaGa! She came onto GMTV and had lace Minnie Mouse ears on and not much else.
"She was great. I love someone that just has fun and takes things to the extreme. She appeals to everyone and is so inspiring."
Kelly added of her continuing stint on breakfast TV: "I honestly think I've got the best job in TV. I get to see movies before they're out, interview stars, talk about big issues of the day - everything.
"As long as everyone still enjoys watching, I'll carry on. I know it will all come to an end at some stage."
