"David and I did propose to each other, but over five years ago!" he confirmed. "We've been wearing engagement rings for ages, waiting for an available date."

"I've already [purposed], he said yes! Thank god!" Burkta said after a Twitter follower suggested he should pop the question to Harris. 

The couple, who have been together for about 6 years, are co-parents to 6-month-old fraternal twins, Gideon Scott and Harper Grace.
