Thirty-year-old Strictly Come Dancing expert Dianne Buswell visited her Instagram page with 724,000 followers and told her fans she had said "yes" to Joe Sugg, 27.
The professional dancer shared a picture of her putting her face on Joe's cheek as he pulled a shocked face toward the camera.
She wrote: "So Joe asked me to move in with him! I said yes … of course I then whispered to him, do you realize how chaotic I can be?
"If you want to see how he asks me, watch his latest YouTube video, it was so cute."
Joe shared a video of the moment when he asked Dianne to move with him on his YouTube blog.
In the clip, Joe showed the fans a gift he had made for the red-haired beauty before asking her the big question.
The gift was a photo frame that contained a Lego version of the couple next to the words "The Love of this Year, Every Year".
The words come from David Gray's hit "This Year's Love," to which the couple danced on "Strictly Come Dancing" last year.
Joe then handed Dianne the gift along with a note and a pen.
Dianne read the note and said, "I have officially invited you to live with me in my humble quarters."
Then she looked at the camera and asked Joe, "What does that mean?"
Laughing, Joe replied, "I knew you would say that."
Then Dianne read the note and said aloud: "Do you want to move in with me, yes or no? Circle your choice. "
The dancer told Joe that his gesture was "very sweet" before jokingly saying she wanted to call a friend.
Dianne then jokingly started to circling the answer "no" before finally circling the "yes" option.
In a recent interview with OK! The magazine Dianne Buswell spoke about her life circumstances at that time.
She said, "No, we do not really live together at the moment, but who knows what the future holds."
She continued her relationship, adding, "We have a lot of fun.
"From the minute we get up until we go back to bed, he makes me laugh because he's so funny, but we have serious conversations.
"We're working on this creative mindset and talking about the adventures we want to do next."
Joe and Dianne have teamed up after moving into the final of Strictly Come Dancing last year.
After weeks of speculation, Joe finally confirmed that the couple is an item in a cute Instagram post.
With his 5.6 million followers he wrote, "I may not have won the glitter ball, but I've won something that's a million times more special."
