After sparking romance rumours with Anita in May, Justin— who's steered clear of the spotlight after exiting the jungle— confirmed he was off the market one month later, sharing a photo of the couple kissing with the caption: "I can't stop falling in love with you."
Moments later, he uploaded another snap with his girlfriend, writing: "Love, I hope you find it and feel it and hold onto it forever and ever."
