MMM...Married!

The last in his young band of brothers to tie the knot, Isaac Hanson weds in Tulsa

From the beginning, Isaac Hanson knew his bride-to-be was a Hanson fan: Like both his brothers, he met his intended at one of the pop trio's concerts. So the night before his Sept. 30 wedding to Nicole Dufresne, 22, in the garden of the Philbrook Museum of Art in Tulsa, the oldest Hanson 25, wrote and recorded a song -- "Every Day" -- just for their first dance. And when the siblings performed a short set at the reception, "he came off the stage to solo to Nikki specifically," says brother Zac, 20, who wed in June. (How they have grown: Best man Taylor, 23, became a dad for the third time last month.) Until midnight, the newlyweds MMM-Bopped with their 300 guests. "The dancing got a bit out of hand -- there was even some break dancing going on," says Zac. But the sweetest moment came long before: "When they fed each other cake, it would've been hard for her to miss Isaac's mouth," says Zac. "It was wide open he was smiling so big."
