JoJo Siwa and Chris Hughes had an affectionate reunion in London after they confirmed their romance by kissing in Mexico.

The “Karma” singer and the “Love Island” alum were spotted getting close when she touched down at Heathrow Airport Sunday morning.

The pair couldn’t keep their hands off each other, with Siwa resting her head on Hughes’ chest as he had his arm around her, per photos obtained by Page Six.

The reality star, who greeted the musician with a bouquet of flowers, kept Siwa close by placing his arm around her shoulder and sweetly holding her hand as they walked through the airport .

The “Dance Moms” alum was dressed down, wearing black cargo pants paired with a denim jacket over a lime green T-shirt and Nike sneakers.

Hughes also looked cozy, sporting a green hoodie, gray sweatpants and white slides.

Their London appearance comes days after they were seen locking lips while sharing a pink-and-orange floaty in the pool at an adults-only hotel in Mexico.

At the time, Hughes, 32, appeared to be holding a drink in his hand as Siwa, 22, leaned in for a kiss.

A source told the US Sun that the “Celebrity Big Brother UK” co-stars “looked very loved-up and as they snogged in full view of other holidaymakers.”

They also “spent their time at the hotel holding hands and looked like a giddy couple in the early throes of love.”

The insider added, “It was nice to see. They were very hands on, not entirely different to how they were on TV just a bit more intimate.

“JoJo seemed totally relaxed, really in love and not in any way the JoJo we see when she’s onstage. They’re just totally comfortable around each other.”

Last week, Siwa shared a PDA-filled carousel featuring Hughes via Instagram after they celebrated her birthday.

In several of the images, the pop star had her head on the “Pointless Celebrities” alum’s shoulder, while another snap showed him with his hand on the dancer’s leg.

“This years birthday week was more magical than anything🤍🪄,” she captioned the post.

“Full of surprises, family time, performing, chilling, laughing, loving, smiling, and good meaningful cries. Absolutely beautiful, wouldn’t change a single thing🤍 a week I’ll remember for the rest of my life.”

The duo first sparked romance rumors while starring on Season 24 of “Celebrity Big Brother UK” in April.

During their time on the reality show, they shared several flirty interactions, including Siwa licking chocolate off Hughes’ shorts.

During an interview on Page Six’s “Virtual Reali-Tea,” the dance star said the moment was “so funny” to her.
