Brent also made an appearance at Berkus' book signing for "The Things That Matter" at Bergdorfs on Dec. Although he is happy now, Berkus faced tremendous sorrow after his boyfriend, photographer Fernando Bengoechea, was killed in the December 2004 tsunami in Sri Lanka.
The designer and his boyfriend were vacationing in southeast Asia when disaster struck.
A tsunami struck and the two were swept into the sea along with debris, animals and other people.
The two grabbed a telephone pole, Berkus said, but lost their grips when a second large wave hit.
After getting engaged on a Peruvian mountaintop, the pair married last year in front of 220 guests at the New York Public Library.
