Appearing on Tuesday's BBC Morning Live, doting boyfriend Joe was asked whether he was "happy" to have his love back home. "I get her back but I mean, I was so gutted for them," he replied.
"They did so well, he got better and better every week. They did an amazing job, I'm super, super proud of them both."
Asked who he will be cheering for now, Joe added: "My winners have just gone so… I mean, it could be anyone. We've had couples this year getting nines on week one - I think it was HRVY which is very rare, I think. He's done incredibly well. There's a lot of people who have been on 'journeys'."
Dianne and Max made their departure from the dancing show on Sunday
Dianne proved there were no hard feelings following their exit. "What an amazing time I have had on that dance floor with you @maxgeorge you have improved week by week and grown so much in confidence," the 31-year-old said on Instagram on Sunday.
"The last dance we did I can't tell you how proud I was and for me was your best dance so far. Thank you for being a brilliant friend to me and being a dream to work with a real genuine down to earth guy.
"Thank you to everybody who has supported us we appreciate every single one of you, and to the remaining pros and contestants go and smash it you're all AMAZING. @bbcstrictly [sic]."
The Wanted singer Max, 32, also took to social media to praise his dance partner. "What a time I had," he wrote. "Dianne, you were an absolute joy. I actually did 4 dances! That'll do for me. I couldn't of wished for a better teacher but more importantly, friend. Every positive I take away from this I owe to you. Thank you."
