Taking after his mama, Giuliana Rancic's son stole the show at a friend's wedding this weekend.

Two-year-old Duke Rancic played the role of ring-bearer and took his role very seriously. The toddler looked cooler than ever in black sunglasses and a sleek dark suit.

"These two," the E! host captioned the pic.Giuliana couldn't help but show off how adorable her son looked all dressed up, as she shared another photo from the wedding, this time with herself included. The leggy star donned a yellow, knee-length satin dress and a pair of sunglasses as she smiled happily at her son.
