So, have they? Yesterday Yarbrough shared an Instagram photo with Stefanovic's sister-in-law Jenna Dinicola with the telling caption "sister sister".
Dinicola, who is married to Stefanovic’s younger brother, Tom replied "love it sister!".
At the time, TODAY host Stefanovic said the engagement would be a short one and they would probably get married "later this year".
Stefanovic and shoe designer Yarbrough regularly share sweet photos together on Instagram, and we can't get enough!
