Jennifer Aniston  flashed her engagement ring as she ran errands around NYC on Thursday just as her onscreen and offscreen friend, Courteney Cox , confirmed big engagement news of her own. Courteney announced on Twitter on Thursday that she had recently gotten engaged to Snow Patrol frontman Johnny McDaid . Meanwhile, Jennifer, who has been engaged to Justin Theroux since 2012, is still battling questions about when she is going to walk down the aisle. Justin joked about the rumors  on the red carpet during the premiere of his new HBO series, The Leftovers, saying that he and Jennifer have "hot feet" about their wedding , as opposed to cold ones. "But we're not going to let you guys know (the date)," Justin added. "We're still happily engaged." Maybe now that we have two Friends weddings on the horizon, Courteney and Jennifer will finally be able to get the entire cast together for that oft-talked-about reunion .
