Looks like little Duke Rancic has a sweet tooth!

Bill Rancic shared an adorable photo of his son Duke reaching for a cookie – or two or three – on Feb. 18. “The Cookie Monster!” he captioned the shot.

He and wife Giuliana Rancic welcomed their 5-month-old son last year, and the happy family recently went on a vacation together to Miraval Resort in Tucson, Ariz. The trio have been spending tons of quality time together, putting family first and career second.

So how else do the couple keep their marriage strong? "We carve out time all throughout the week to be together," Giuliana, 37, says.  And based on the frequency of twitpics that we see of their little guy, it seems Giuliana and Bill can't get enough of their tiny tot.
