Kirk and Cami have spent the last week in Sin City together, but the long-distance couple - who were initially rumoured to just be friends - have now been forced to wave goodbye to each other as the trip has come to an end.
Throughout their break, Kirk and girlfriend Cami have shared a selection of holiday pictures on Twitter which show them both soaking up the Vegas atmosphere.
But as they fly home - with Kirk heading back to Essex and American Cami to Florida - the couple have used the social networking site to confirm that they are definitely an item.
Kirk tweeted: "Just dropped @CamiLiModel off at the airport and I'm not gonna lie, it's one of the hardest things I have done in a while! :-("
Cami also tweeted: "@kirk_official I'm leaving my heart in Vegas. Damn, I can't remember the last time I cried." She later added: "Already planning my trip to London in my head #misshim."
The couple appeared to have a great time in Las Vegas, posing in a giant red stiletto and joking around with a life-size cutout of Alan from the movie The Hangover.
Yesterday, Kirk and Cami even got matching skull and cross bones tattoos, proving that they are definitely serious about each other!
Something tells us it won't be long before they are reunited - perhaps even over a drink in Essex haunt Sugar Hut!
