Joe Sugg and Dianne Buswell are "inseparable" after she split from her boyfriend.
"Strictly Come Dancing" professional dancer Dianne's relationship with actor Anthony Quinlan ended earlier this month and she has been spending more and more time with her "Strictly" partner Joe since then.
A source told the Daily Mirror: "Joe and Dianne are completely inseparable - they are spending every waking moment together, even after rehearsals.
"Joe has even been inviting Dianne back to his house and they have been staying up to all hours chatting and hanging out."
A spokesperson for Dianne announced the split, saying: "Due to their busy schedules and distance, they have split, but still remain really close friends."
Joe, 27, previously revealed Dianne, 29, has been hugely supportive during his time on the show and has been offering words of encouragement and even praised his long neck, which has caught the attention of fans on social media.
He said: "My pro partner Dianne says that I've got a good ear for music and my rhythm is getting better.
"She also pointed out that I have a long neck, which is good for ballroom, the style I'm most looking forward to. There's already five Twitter accounts called Support Joe's Neck, which shows what my fan base is like!"
Although Joe has a huge group of younger admirers, he admitted he was prepared for the older generation to be more unfamiliar with his work.
He said: "I was prepared for the "who's he?" backlash when they announced the line-up. But I do appreciate that there's a whole generation who don't know who I am.
"There will, however, be youngsters in their families that do. And that's the reason I'm doing "Strictly". If I can help to bring families together on a Saturday night, that's a massive win in my book."
