Pixie, 23, is favourite to win the competition, but felt she had to stand up for Judy, 55, after viewers started to become irate that she had survived so far into the competition.
Judy was voted off the show last night.
Speaking to the MailOnline, the pop star said: “We all love Judy. She is such a lovely person. She's really bubbly and kind and she always brings in chocolate and shortbread and just gets on with everyone.
“She's definitely someone I love having around. So hopefully we're still in it together [after this weekend]. I think she's been working really hard.
“And it is pretty hard for someone who's never done anything like this before to go out every Saturday night and perform and do proper choreography. And she's doing it with a smile and not taking herself seriously. I think that's why everyone loves her.”
Pixie is particularly close with the other girls in the competition, and hopes one of the ladies walks away with the Strictly trophy.
She said: “I would be happy if it was one of the girls [who win] because us girls are really close. But there's not one person who I don't get on with who was in the competition from the start. I really get on with everyone.”
