JoJo Siwa surprises boyfriend Chris Hughes with a HUGE dance tribute in her new music video as they mark a 'beautiful and perfect' year since they met on Celebrity Big Brother

JoJo Siwa has paid tribute to her boyfriend Chris Hughes in spectacular fashion, as the couple mark exactly a year since they first met on Celebrity Big Brother.

The pair formed an unlikely romance after becoming close friends on the ITV show, with JoJo previously declaring they've already discussed marriage and starting a family together.

And with JoJo, 22, and Chris, 33, both marking a 'beautiful and perfect' year since their first meeting, the Dance Moms star has now unveiled her musical tribute to him, with a new song called Serendipity.

JoJo even surprised her boyfriend Chris in the video for her new song, which showed the unknowing star heading to a theatre with JoJo's parents Tom and Jessalynn, under the assumption they were about to watch a show together.

However once the curtains opened, Chris was greeted with both his girlfriend and  a troupe of 86 dancers performing the song.

Both stars also marked the anniversary on Instagram, with Chris sharing a clip of himself and JoJo mere seconds after they met on Big Brother.

He captioned the post: 'One year ago today, I discovered your existence.

'The first thing I ever said to you was, ''you're very colourful'', and that colour still radiates every day! It's flown by, feels like yesterday I got out the bb house, crazy universe.'

JoJo showed her appreciation for her boyfriend in the comments, writing: '1 beautiful perfect year.

'Feels like yesterday and 10 years ago all at the same time. Forever grateful to that house for so many reasons, but there is definitely one special reason.'

JoJo shared her own tribute to Chris, writing: 'A year ago today we said our first hello, our first hug, our first laugh… the beginning of so many. So forever grateful to the walls of that house.

'One year since walking into the Big Brother house, one year since my smile grew in a way I didn’t know possible. Today, I’m reminded of the moment that quietly changed everything.

'The only word to explain what happened on this day a year ago… Serendipity.'

JoJo recently admitted she was 'lost' before going on CBB as she reflected on the time since meeting her boyfriend Chris.

Alongside a gallery of photos from CBB, she wrote: '10 months ago I entered the house that changed my life for forever.

'Three weeks with some of the best strangers I’ve ever met, three weeks of letting loose having fun, and three weeks of not even realizing it, but finding myself and comfort and pride within myself.'

She continued: 'Right around a year ago, I knew I was lost in who I was, but I wasn’t sure how to fix it and find who I was, I don’t know if that makes sense but if you think about it on a deep level, it will make sense.

'A love greater than one can imagine, a bond strong, stronger than I knew was possible. Where it began.'

The couple have already described each other as 'the one', with JoJo now saying that starting a family with Chris is her 'destiny'.

Speaking in an interview, she explained how they have spoken about children and discussed her plans.

JoJo said: 'I have names that I really, really like and that I've spoken to him about. But I've never said them publicly.

'But now that we're this much further along, I have a relationship with his family. He has a relationship with my family. It just feels like destiny.'
