Brian Austin Green and Tiffani Thiessen together again? OMG! On Thursday, the former couple went to a private event hosted by Sandals Resort to support the company's eponymous foundation. Tiffani brought her 15-year-old daughter, Harper, to the function and bumped into her old flame at one point! Fortunately, it was not an awkward run-in! She and Brian even snapped pictures together during the rare reunion! Related: Kate & Jon Gosselin's Rarely Seen Daughter Mady Reunites With Sister Hannah!
