Roger Clinton, former President Bill Clinton's half-brother, says he was blown away seeing Chelsea walk down the aisle over the weekend.
"She was more beautiful than ever," he tells Entertainment Tonight of the former first daughter, 30, who wore a stunning Vera Wang gown.
Adds Roger, "It was a great night." Chelsea exchanged vows with longtime beau, investment banker Marc Mezvinsky, 32, Saturday in a lavish ceremony at the Astor family palace in Rhinebeck, N.Y. "Marc gave an eloquent speech about his love for Chelsea," a wedding guest tells the New York Daily News.
"At the end of his speech, he ignored the rest of the room and looked very intense. He looked right into Chelsea's eyes. Oh, it was something. The whole room was quiet. You could feel the energy in the room. He impressed a lot of people."
Former President Clinton, 63, couldn't hold it together, added another guest. "Bill's chin began quivering and he tried to fake a smile as a tear came down his cheek," another guest told The News. "He whispered something into Chelsea's ear, and she wiped the tear off his face. It was so touching. There wasn't a dry eye in the house."
He cut in after the newlyweds had their first dance to Jerome Kern's "The Way You Look Tonight," performed by the wedding band, the paper reports.
Another wedding highlight -- when the father of the bride toasted his daughter.
"Bill's toast was vintage Bill Clinton," a guest said. "He spoke quite elegantly about what it was like to welcome Marc into the family."
Added another, "It hit all the right marks. It was perfect."
