Donald Trump Jr. is sharing more details about his engagement to Bettina Anderson. "So we walk in, they had the whole thing decorated," Trump, 47, told attendees at a surprise birthday party for his fiancée, 39, in Palm Beach, Florida, as seen in a video shared by friends John and Diane Sculley via Instagram. Trump added that he kept trying to "distract" Anderson, who was "talking about other stuff," and get her to look away from him so that he could pull the ring out of his coat pocket. "And she keeps looking at me," he continued. Don Trump Jr.
