Rob Kardashian and Rita Ora
Though nowadays they're an official couple, before they got serious, Rob Kardashian tweeted at Rita Ora semi-constantly. During the courtship process, Rob tossed out some outlandish tweets, including this one where he referred to the British singer-songwriter as his wife.
Sure, this happy couple may have recently got matching name tattoos, but don't count your chicken before they hatch, Rob. Remember Kim and Kris? So do we.
