For Reggie Bush
's lavish Saturday wedding
to Lilit Avagyan in San Diego, it was the bride who scored the most memorable moment at the reception.
"Lilit performed a dance for Reggie," says a source of Avagyan, a professional ballroom dancer. "It was so beautiful! Reggie had a smile on his face I can't even describe."
Clad in a Tom Ford tux, Bush, 29, was all smiles all day as he exchanged vows with Avagyan, 26, who wore a wedding gown designed by Galia Lahav
. Their 14-month-old daughter, Briseis, served as the flower girl at the ceremony held at the Grand Del Mar.
Afterward, more than 250 guests – including Cheryl Burke
, Stacy Keibler
and Brody Jenner
– witnessed the newlyweds perform their first dance to "Georgia" before enjoying live musicians performing big band tunes.
As evidenced throughout their wedding weekend, says the source, "they're so in love."
